System Configurations
First things first, you can see that prices are essentially equivalent, but that is due in part to the components we selected. The Pentium D platform costs a bit more than the AM2 platform, as does the Sempron 754 system. We could always spend more money to add additional performance, but we're trying to stick to the upper end of the budget price range. We could have upgraded the AM2 processors slightly, for example by switching to an Athlon 64 3000+, but the difference in performance really isn't that substantial. We're not intentionally trying to handicap AM2, but the simple fact of the matter is that Intel has much better prices on lower end components. The Pentium D chips are all priced much lower than the equivalent Athlon X2 chips, to the point where we simply wouldn't consider getting anything but a dual core processor if we were to buy an Intel system. That said, the price cuts on the Athlon X2 3800+ will drop that to the point where you can actually consider it as an upgrade. It will still cost more than the Pentium D 805, but it will simply reverse the situation from now where our "Budget Pentium D" costs more than the "Budget Sempron AM2" configuration. (And for another $30 or so, you could then upgrade from the X2 3800+ to the Core 2 Duo E6300, and before you know it you're spending well over $1000 on your "budget" computer....)
You can see that most of the other areas are equivalent. All of the motherboards are reasonable budget offerings that still offer a decent amount of overclocking capability. The socket 754 motherboard is clearly cheaper, but it's also older and has fewer features than some of the newer boards. Looking at the motherboards, the Biostar TForce 550 is clearly superior to the other two. Gigabit Ethernet, support for all AM2 processors, high definition audio and a nice, clean layout make the price of $85 more than reasonable. The other two motherboards only include 100Mb Ethernet, but unless you have a gigabit switch it won't matter. They also include lower quality AC'97 audio solutions, but the onboard audio is still sufficient in most cases for people on a budget. If you're interested in getting better quality audio, simply adding a Chaintech AV-710 for $23.00 or a Creative Labs Audigy SE for $28.00 is a definite improvement over AC'97 audio, though when you're talking about budget PCs there are many $20 upgrades that can improve various aspects of the system, so for this article we're sticking with the integrated audio options.
The graphics card was chosen as a very reasonable budget gaming option. The GeForce 7600 GT packs a lot of bang for the buck compared to other GPUs currently being sold. X1800 GTO is also competitive in this price range, but the 7600 GT cards have much better availability. Note that while we used an XFX 7600 GT XXX, there are other 7600 GT cards that are priced a bit better, like the EVGA models; mail in rebates are also widely available, knocking off another $30 or so from the price of most 7600 GT cards. That means you can get some of the models for about $140 after rebate(s). If you're thinking that $140-$195 on a graphics card is far from being a "budget" selection, our reasoning is that you're building a budget PC, but you also want to be able to play games. We assume that most people need a PC in their home these days, so when people consider a gaming PC versus one of the consoles like an Xbox 360, they often end up concluding that the consoles cost a lot less. We figure you're already spending about $500 for a PC whether or not you have a gaming console, so really you're only spending another $150 to turn your PC into something that can play most of today's games. If you would like better video performance, of course, you could also go with a faster graphics card and spend more money. Prices on the 7900 GT cards have dropped to $265 before rebates (about $240 after rebate), so graphics performance scales almost linearly with additional money. If you don't need graphics performance at all, you can of course go with an integrated graphics solution or something cheaper.
If you're wondering about the memory choices and memory timings, there are many options available that are worth considering. The Patriot RAM used in the Sempron 754 motherboard was chosen because it was available, and because TCCD RAM remains highly regarded in the world of DDR memory. Consider it something of a handicap for the old socket 754 platform; it will also make things a lot easier when it comes to overclocking, so we're giving socket 754 every chance to maintain pace with the faster newcomers. If you opt for value DDR memory, you will need to use various memory ratios in order to be able to overclock the Sempron 754 chip, so overall performance will likely drop 5-15%. We began DDR2 benchmarks using 2x512MB G.Skill PC2-5300, but given the price discrepancy between socket 754 and the other platforms, as well as the fact that we are overclocking, we switched to the OCZ PC2-6400 as a moderate upgrade. It is certainly possible to overclock using value DDR2-667 RAM, but it is almost always less of a hassle to overclock with higher-quality memory. Depending on the memory you purchase, you may or may not be able to run the same timings we achieved, and in general we found that all three budget boards required slightly more relaxed timings than high-end enthusiast motherboards. With more time and effort we could probably improve performance slightly, but we're really only talking about minor differences anyway, and as we'll see in the benchmarks the memory subsystem isn't normally a bottleneck for the systems. The AM2 configurations are also somewhat interesting, in that the memory dividers do not provide exact memory speeds in most instances. For example, the Sempron 3400+ is really only running the memory at DDR2-720, as there is no integer divider to get DDR2-800.
There will probably be complaints about using a cheap, generic 400W power supply. This power supply was purchased for exactly that reason six months ago, and I was hoping to cause the power supply to fail by putting a constant load on it. It has been happily running the overclocked Pentium D 805 system with two instances of Folding@Home 24/7 for most of that time, without any difficulty. We'll get to the power numbers later, but basically the entire system power draw is still under 400 W (though just barely in certain stress situations), and we are only using a single hard drive and a budget processor. A better motherboard, heatsink, power supply, memory, etc. would likely improve our overclocking results, but all of those expenses would defeat the purpose of building a budget system. Yes, the power supply is a lower end model, but sometimes that's all you really need. Many OEM systems also use relatively low-quality power supplies, and while a few people might encounter difficulties, most of these PSUs will last several years. If/when it fails, you will probably be ready to replace your entire system anyway. One last comment on the power supply: we really have no problem using this power supply with the Sempron systems, but especially with the overclocked Pentium D system, getting something a bit nicer would be prudent.
Finally, you can see that we included a couple of upgraded AM2 motherboards. We used the Gigabyte board to retest the Sempron AM2 chip, as the results we achieved with the Biostar board were lower than expected. We also included a system running an "Athlon X2 3800+" (simulated) processor using a Foxconn 590 SLI motherboard. The actual CPU is a 5000+, but lowering the CPU multiplier to 10X generates performance identical to the X2 3800+. We "overclocked" this particular CPU to 2.6 GHz for now, which seems reasonable for normal X2 3800+ chips (especially considering that's what most people get out of socket 939 X2 3800+ processors). The reason for the inclusion of this CPU is that it will drop substantially in price in the near future, and we felt it was only fair to show how the cheapest AM2 dual core processor performs in comparison to the cheapest Pentium D processor. It will still cost more than the Pentium D 805 even after the price cuts, but there are certainly other advantages which we will cover throughout this article. The Foxconn motherboard was used with this processor (as opposed to the Gigabyte 590 SLI board) due to the fact that the Foxconn board properly supports CPU multipliers with the latest AMD CPU driver installed. The Gigabyte and Biostar motherboards both revert to the default CPU multiplier once Windows loads, which obviously affects our ability to overclock or to simulate a lower speed processor. The AMD driver is required in order to get correct results from PCMark05, and the performance differences between the Gigabyte board and the Foxconn motherboard are otherwise insignificant.

I'd be more inclined to drop to a 3200+ and spend the money for a 7900 GT if you're looking for gaming performance. Get that with one of the 570SLI boards (yeah, there goes the budget) and maybe 2x1024MB of DDR2-667. That'd be a nice mid-range config.Avalon - Monday, July 10, 2006 - link
I've also had good luck with Apex/Allied case/PSU combos. Bought several a couple years ago for some AXP systems, and they're still going strong. Generic isn't always bad. Just powmax ;)DrMrLordX - Tuesday, July 11, 2006 - link
Sadly, the Apex case + PSU combo I got for my current system didn't work out well at all PSU-wise. I got the Apex TU-124 and it came with a dinky little 350W PSU that I immediately removed from the case and replaced with my old Antec Smartpower 400W PSU. The Antec had previously been in my 1 ghz Tbird rig and is still running, while the PSU from the Apex case went into my Tbird rig when I upgraded. I later gave away the Tbird, only for the system to die after about 6-8 months of operation in new hands. The Tbird was put together in early 2001, and can you guess what component died after I gave it away? The PSU.I'm not sure what it was about that Tbird rig, but it killed two generic PSUs (the original that came with the case I bought for it and the one from the Apex case I bought in March 2005). The Antec PSU, however, worked just fine. I got that one back in 2004 or so when Antec was still putting out PSUs with high marks for reliability.
Operandi - Monday, July 10, 2006 - link
"Generic case with iCute 400W PSU (Purchased Locally)"Generic PSUs and cases should never be recommended, particularly PSUs. Reliability is not something you can benchmark with one sample in six months time. If you can't afford a $50 InWin, Evercase, or entry level Antec case along with a $30-50 Forton-Source PSU you should probably be shopping at Dell or HP which will almost certainly get you more reliable machine.
I believe AOpen cases are still shipping with Fortons built in, so that would be a very good choice. Antec case PSU/bundles while not the best are fairly decent and that really should be the entry level even for a low budget machine, not generic garbage.

I do grow tired of the Power Supply snobs. Yes, yes, we all know that there are some really lousy power supplies out there bundled with cheap cases. There are also many perfectly good power supplies bundled with cheap cases. For the purpose herein, *most* generic power supplies will work just fine.Anyone looking for a low-cost case that comes bundled with a reasonably good power supply, check out Athenatech:
http://www.newegg.com/Product/ProductList.asp?Subm...">http://www.newegg.com/Product/ProductLi...rchInDes...
I've used several of these cases, including quite a number of the MicroATX cases which include Sparkle power supplies.
mindless1 - Wednesday, July 12, 2006 - link
There are snobs and then there are SNOBS.Fact is, we dont' actually have sufficient data about longevity of generic PSU with modern, higher wattage system configs. That your 4 year old box has now 4 years running off a different generic is no evidence that another generic will run a modern system pulling 50% more current.
DrMrLordX - Tuesday, July 11, 2006 - link
Sparkle is hardly generic, though. Those are rebranded Fortrons.mesyn191 - Wednesday, July 12, 2006 - link
Yup, FSP/Sparkle are quality PSU's that are cheap. Inwin aint' bad either.OP is really a PSU snob he just doesn't know it!!
JarredWalton - Monday, July 10, 2006 - link
Cases are something you can go out and grab whatever you really want; I bought this locally because that was convenient 6 months ago. Sorry if this isn't clear, but the case/PSU was listed for disclosure purposes. Yes, there are better choices, but that's what was used for these benchmarks. Fotron Source would be a great choice for a 400W-500W PSU that would certainly be better than the iCute I used. I hoped people would understand that the configurations were a look at some available parts and not a specific recommendation, i.e. get a different GPU than the XFX, possibly different RAM, the Tforce 550 has some performance issues right now....Basically, I built three budget platforms that more or less were priced similarly, and looked at how they compare in terms of performance. Out of the three, I'd take the PD805 for my purposes. Makes a nice addition to a folding farm. :)

The title says budget PC, but the article makes clear it is a "budget gaming system" that is being talked about. So the title should be changed to budget gaming system or budget gaming PC.
