Doom 3 has been quite a learning experience for all of us at AnandTech. Some of the things that we expected to find just never panned out when we ran Doom 3, such as the concerns that Doom 3 would not run on most systems. In fact, Doom 3 will run on most of the recent systems out there. Other things were a real surprise, like the fact that the ATI 9800 PRO is a medium resolution card to Doom 3 and it is GPU bound above anything but base performance levels. Doom 3 eats video cards for lunch, and while you will get a usable screen with most video cards, you really have to feed it top-end video for best results.
You have already seen the Doom 3 Week reviews, but in case you missed anything, you can find the answers in the earlier reviews this week:
Doom 3 Sound Guide
Doom 3: CPU Battlegrounds
Doom 3 Graphics Deathmatch
The purpose of this Doom 3 Buyer's Guide is take all that we've learned in these reviews and make some basic recommendations for a killer Doom 3 system. Since desires, designs, and pocketbooks are different, you will find three recommendations here - Performance, Mainstream, and Value. Because we've covered a lot of the components here in our ongoing Buyer's Guides, we will concentrate on the unique components for Doom 3 - mainly the CPU, motherboard, graphics card, and memory. The rest of the components have been pulled from our most recent Buyer's Guides, which you can find under the "Guides" tab at the top of the page.
