I tried placing my PNY Verto GeForce FX graphics card into my Dell Dimension E310 into the PCI slot, but it seems like it won't fit. Will any graphics card fit into the Dell Dimension E310, or will I have to get a new computer? By the way, I want to get a graphics card that will play BF2 (the PNY did for me awhile ago on my older computer), and also can play COD4 (integrated Dell one won't, I don't know about the PNY one).
