Hi, I have a Dell Optiplex GX110. I would like to add a better Graphics card to it to improve the graphics on it. I have no Documentation for it as I bought it used. Our local Walmart(the only store close-by that carries any upgrade parts) has a NVIDIA card which I believe is a pci-slot-card, and they also have in stock what I think is called a ATI RADEON 128 MB card. Would it be possible for me to install one of these in my DELL and make it work? Would I need to change any jumper settings on the Motherboard etc? Any suggestions on this would be appreciated. Thank You!
