Ok guys so which GTX 770 should I get, I was just about to buy a 680 for the amazing price overclockers had them up at, but I was too slow
.
I was thinking one of these:
http://www.overclockers.co.uk/showproduct.php?prodid=GX-015-IN
http://www.overclockers.co.uk/showproduct.php?prodid=GX-219-EA
I only have a 620w power supply so I don't want a card that uses ridicules amounts of juice.
Any help would be greatly appreciated.
