4890 vapor x at 1000/1100
I'm debating on whether or not I should get the gtx 560 or 570. It needs to be nvidia because I like having physx. I am planning on sli'ing whatever I get in about a year from now. So for example if I buy a 560 now, a year from now ill buy another one and sli it. Im not sure if my corsair power supply could handle 2 570s? If it cant then do you think I should just get a 560?
