Whoa! That would be so awesome! The card I had in there was a e-GeForce 8600 GTS, so I'm pretty sure I have a PCI-E x16 card slot. (Seems to be so, looking at everything inside the case and comparing it to pictures online... also found my motherboard specs and it says that yes, I have a PCI-E x 16 slot. Hooray!)

Are you sure you don't need it? I hate to seem like a beggar, but it would be an upgrade and would definitely save me a bunch of money. Let me know how much it would be to ship, and I can at least PayPal you for the postage!
