I've only read like half this thread but I will confirm that the gtx 570 kicks ass I have this one

it's a rev2 pcb so it's a bit shorter than the original 570, I'm using a relatively tiny midtower and it fits with acceptable temps

also many evga boards come with a lifetime warranty but you have to register for it within 30 days of purchase, warnings are printed to this effect in loads of places on the docs, box and board itself but retards be stupid
