Hi all -- I have a Dell Dimension 8300: Intel Pentium 4 CPU 2.6 GHz 2.00 GB of RAM 80GB Harddrive Currently I have an nVidia GeForce FX 5200 graphics card but I want to upgrade. I do a fair amount of gaming, not a great deal but I do enjoy a higher performance, I also recently got BioShock which I was looking forward too but requires a higher performance card. Does anyone have any idea on what cards would be compatible with my system and any recommendations on what would be the best fit. I do tend to prefer nVidia cards but am in no way constrained by that. I'm happy to spend a little more for that added performance, I would rather get something better now and not have to upgrade again for a while. Thanks in advance!
