Performance CPU

For the best performance possible in Doom 3, the Athlon 64 FX53 is an easy choice. The FX53 tops all of the benchmarks in the Doom 3: CPU Battlegrounds review. This is also why the FX53 was our reference CPU in Doom 3 Graphics Deathmatch. The Athlon 64 is currently the fastest processor that you can buy, the Dual-Channel Socket 939 is the top-performing A64 Socket, and the FX is the fastest 939 processor. The FX series also has the distinction of being the only Athlon 64 processors that are completely unlocked. That means you can adjust multipliers both up and down, to obtain the highest possible speed at the fastest DDR400 memory timings, or to obtain the highest FSB that your high speed memory can run or your CPU can reach. Most FX53 that we have tested can easily reach 2.6GHz at default voltage with air cooling, and some do even better. This pegs performance at a clock speed that we won't see in a retail CPU until late this year.

Performance Motherboard

If we could find it for sale anywhere, our recommendation would have been the excellent MSI K8N Neo2, which was our Gold Editor's Choice in our recent Socket 939 Roundup: Battle at the Top. However, just as we were going to press, we received word of further delays in retail availability of the K8N Neo2. Quite frankly, after two months of recommending the K8N Neo2 and no one able to buy it, we are not going to recommend again a board that you can't buy today. The K8N Neo2 is a great board, if you are willing to wait for it, and the nForce3-250 chipset is a bit faster with an nVidia 6 series video card than VIA.

Of the boards you can buy today, the Abit AV8 PRO and Asus A8V Rev. 2 were our Silver Editor's Choices in the Socket 939 roundup. The Asus Revision 2 is not yet in the market, but should be available in the next couple of weeks. The A8V that we have seen for sale are still the original revision, which performs quite well at stock, but does not have a completely reliable AGP/PCI lock. If overclocking doesn't matter, then the current A8V is an excellent choice, but if you want to overclock, wait for the A8V Revision 2.

The Abit AV8 is available today and is quite a value at $121. The AV8 performed very well in our Socket 939 roundup and will work very well with the FX53 and up to 4 Gigabytes of Dual-Channel memory. Even though the AV8 is one of the most reasonable Socket 939 motherboards that you can buy, it still includes Firewire ports, 6-channel on-board audio, and 2 SATA ports that support RAID. It also features one of the best selections of overclocking options that you will find on any Socket 939 board, so you can squeeze the most from your Doom 3 system.
