Just about to send back a Gigabyte Windforce Vega64 because it wasn't stable: Hard locked with fans going nuts after an hour of Valley benchmark. Locked after leaving Warhammer2 on the campaign map overnight. These are not problems my six year old MSI 7970 Lightning Edition card suffers from. It is notable that the Gigabyte is lighter in weight, and has a 'feeling' of engineered to a price. The existing three year old hardware of a Fortress05 and Silverstone 750W gold PSU should provide plenty of power/ccoling. After all it has coped with a 280W card just fine. I have read a review of the Windforce that discussed similar problems, so I have no interest in getting another one. The only other AIB vega that will (definately) fit is the Asus - To your knowledge do people consider this card utterly reliable?
