Hey Guys I'm looking around and i realize to run a descend vid card for my Dell Dimension 4700 im gonna need a better PSU (Like 40$ better - Expensive b/c Dimension 4700 only takes BTX PSU's) so my plan to get an extra gig was canceled. I'm thinking somewhere on the low-GeForce 7 series or high ATI Radeon 1k series. Can an ATI card above X1550 run with only 1GB RAM (A 512 MB card)? Can a NVidia 7600GT run on that? Would i be better off with a 7300? Or just a X1550? My board has 1 PCI-e x16, 1 PCI-e x1, and 1 or 2 PCI slots. Not too shabby for casual gaming. (I don't need latest games, just something that can run DX 9.0c) Any GPU suggestions would be much apprichated. I'll try to answer any questions a.s.a.p. Thanks to all who reply!
