Alls I can say is I spent $774.89 (CDN) on an ATI Radeon 9800 PRO 256MB and Im still waiting to be impressed. The only difference between the low, mid, and high end platforms of video cards (that I've noticed) is how much frames per second they put out. The Image Quality is more or less the same. Some people can handle 5-10FPS (1GHz GF1) other people like to have in the 3 digit margin (3GHz 9800). I could care less as long as when I click my mouse to shoot, the gun responds in the same second. Great move carmack did though, now more people will buy the game and he can fill the pool in his backyard with $100 bills instead of $50's.
