DOOM 3 hardware guide released
The cold, HardOCP has posted its DOOM 3 Hardware Guide with loads on info on how DOOM 3 plays on various sorts of hardware configs. The goal is a little different from a simple benchmark comparo, so I'll let them explain:
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.
If you are wondering how well your rig will play the game and what kind of quality compromises you'll have to make for playability, this should give you some idea.
