I'm Aaron and I'm getting back into the pc gaming world after a couple years absence. I have to say things have got even more confused since then and I'm having a little trouble getting all the new technology compatibilities straight. The nvidia 8800 and newer cards are all pcie x.16 2.0, so does that mean they are not compatible with a pcie x.16 mobo? If so, I am planning on going dual sli 8600gt 512mb on a board that supports 2 pcie x16 slots. Does that sound like a good idea? If no, what would you suggest?
