The DOOM3 Hardware Guide

HardOCP has posted The Official DOOM 3 [H]ardware Guide, testing a whole bunch of hardware configurations to show what kind of performance you'll be getting in id Software's latest.

This guide is not an attempt to crown a king in the realm of hardware, and no direct comparisons are going to be drawn on any of our graphs. Our goal here is to help you understand where your system is positioned in terms of playing DOOM 3 and to help you choose an upgrade that will make a real difference and offer you the greatest improvement in gameplay for the money spent.
