MeteorsRaining :
EVGA is trusted, but make sure you get ACX 2.0. Right now however, MSI Gaming is ruling the roast for SLI, as its the quietest and most OCable 970, which'll help a lot in SLI.
Roast :
and its most quiet, not quitest.
Sorry, do not normally correct people on here but that was a bit much with the roast.
OP : At the moment the EVGA should be avoided till they fix the issues they are having with their cooler.
These 2 are great alternatives :
MSI Gaming.
Asus STRIX.
EDIT : Zotac makes some great graphics cards too, but they tend to be a teensy bit louder.
