Someone I know at school offered to sell me a used (8 month old), factory overclocked Nvidia 260 GTX graphics card for $100. I am currently using an NVIDIA 8800 512mb GT. I'm wondering if this card is likely to be compatible, and I'm not sure, because I usually don't pay much attention to my computer if it works. I have an ASUS P5N-E SLI motherboard. Is there any other info I'd need to know if this would work?
