And if I gonna buy a second 570 for SLI, does it need to be exactly the same card, manufacturer etc? The one I have today is Asus GeForce GTX 570 DCII 1280 MB
What should I watch out for?
What about cooling?, they will stay very close.
Is there any O.C options/possibilities, for this card? with or without SLI?
And my PSU is Corsair TX750M will that be good enough for SLI?
