Yea and dont say "Which should i get: Nvidia or ATI" Cos theres no better one. Give a budget and your specification. Im not an ATI Fanboy but i got the X1900XT based on my budget and how well it performs. Not because i chose ATI. In fact soon il upgrade to the GeForce 8000 if i need to. But in future Give a budget and specification i.e PCI-Express and play FEAR, BF2 Etc.
Yea a 7800GT will be nice.
