What video card is compatible with my computer?

I have a Dell Optiplex 745

Intel(R) Pentium(R) processor D CPU 3.4 ghz

3 gigs of ram

32 bit op system

dont know what kind of power supply I have, and I currently have a q965/q963 chipset family video card that sucks

I want one thats ok for playing games like killing floor and Team Fortress 2

please provide info on how to install a new video card.|||Any PCI Express or PCI express 2.0 graphics card will do.



Since your slot is PCI-E 1.0 not 2.0, don't get a very expensive card as you would not be exploiting its full potential anyway.



Basically see how much you want to spend and go from there.|||Power supply Guide ...
