Not much difference. GPU chip is exactly the same in all cards, only difference is the PCB board and all that's on it, Caps, RAM, etc. That detail can push a certain graphics card above the others, but not by much. Taken into consideration as well is the manufactures customer service and any special deals they may offer, as well as warranty. EVGA has lifetime warranties, great cust. service, and trade up deals, thus they're are considered one of the, if not the, best.
