I was pretty worried like everyone else wondering if my old ATI 9700Pro could handle Doom3. Checking newegg every few hours to see if they have either a x800xt or 6800 Ultra/GT in stock. Well don't stress yourself if you have a 9700 Pro or better. I ran D3 on Tigershark at 1280x1024 medium detail and looks great and plays smooth. High detail does just enough framing to be annoying. ShuttleOne with a 9700Pro AIW with 512 Ram at 1024x768 high detail looks fantastic with no framing. Both resolutions are native for my LCD's. So unless you really need a new video card or just doing your normal upgrade don't worry so much about Doom3. I do run a very clean and organized system so your results may vary.
