I am choosing ATI because I have had problems with my NVidia card in the past. I have a 5900 Ultra and the heatsink decides to fall off one day and unknowingly I continued to play games until I recieved a warning message that my video card was dramatically over heating. I sent it back because it would'nt function. I got a refurb card and guess what? Bad refurb. I was really disappointed. I will be sending it back and selling the new refurb I get if it will even work. So I'll be going with ATI. I sold my other PC that the card was in to my brother. Now I'm getting a brand new one! AMD 64Bit 3000+, 1 Gig Corsair XMS Ram, MSI K8T Neo Mobo, and ATI Radeon X800 Pro. Should be good to go for a long time. :-D
