A friend of mine is offering to sell me a used NVIDIA 1792mb GTX 275 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 and a 600 watt power supply. Is there any other info I'd need to know if this would work? I can get the specific name of the power supply if I need to.
