Our Best Buys
Our top pick among the Intel-based motherboards is the $149 Asus P5N-E SLI. The only model we looked at featuring nVidia's nForce 650i SLI x8 chip set, it did just about everything well. It still has a few minor weaknesses, however; for instance, it provides only three one-eighth-inch analog outputs on the back panel, limiting you to 5.1-channel sound (instead of 7.1) unless you use the rear-panel digital coaxial connection or internal analog audio header. The second-ranked ECS nForce 570 SLIT-A (v5.1) impressed us with a very attractive price ($95), but it uses an older nForce 570 SLI x8 chip set and is the only board in our roundup that lacks FireWire ports of any kind.
In contrast, the $249 Asus P5N32-E SLI, using nVidia's nForce 680 SLI x16 chip set, missed a spot on our chart largely because of its relatively high price.
Among AMD-based boards, Gigabyte's $170 GA-M59SLI-S5 won our Best Buy nod, combining state-of-the-art and legacy peripheral ports with a nice price. A pair of AMD-based boards failed to rank. The $165 Asus M2R32-MVP's performance numbers were a hair slow in a field of fast competitors. And DFI's $190 LanParty UT NF590 SLI-M2R/G, while an excellent overclocker's board, just missed out because it allows a maximum of only 4GB of memory and lacks legacy ports (which may not be a big deal, but other boards continue to offer them).
Power users with AMD leanings should note that overclocking is the raison d'
Despite not making the chart, the Intel DG965WH remains a very good choice for a budget system, where overclocking and high-end graphics aren't as great a concern. The board's integrated GMA X3000 graphics chip ran Vista's Aero interface satisfactorily, and it saves you the expense of buying a graphics card.
Choosing a CPU
Previous testing has shown that Intel's Core 2 Duo has shoved AMD's chips into the backseat in performance. (See "Intel's New Core 2 Duo Processors Run Blazingly Fast in PC World Tests.")
For our tests we used an AMD 2.6-GHz Athlon 64 X2 5200+ that costs about $300. Our Intel test bed used an approximately $500 2.66-GHz Core 2 Duo E6700.
If you want maximum performance, buy a top-of-the-line Core 2 Duo or perhaps a quad-core chip (see "Quad-Cores Need Multithreaded Apps"). If you don't want to pay Formula 1 prices and you're content with mere NASCAR get-up-and-go, opt for an AMD processor or a cheaper, second-tier Intel CPU.
