I know this probably has been asked 1000 times, but I was wondering if anyone be kind enough to recommend a power supply for the 8800GTX, I am not very familiar with power supplies I currently have the stock power supply that came with my antec case (500W), I have 3 optical drives and 4 HD (2 74gb raptor), I also have a few fans in the case, please recommend something that would allow me to run this with a single 8800GTX but I am planning on buying a second one to SLI in like 6 months. tia. oh by the way the board is the evga 680i.
