If your playing on 3 monitors deffinelty get the 7950 if not?well get the 7950 anyways they are faster then the gtx 680 overclocked plus you get 1 gb more of vram.no brainer
Problem is both overclocked at max the 7950 is still within 10% compared to the lead the gtx 680 has over it stock for stock a gtx 680 is a waste of money and from my understanding 680's overclock like crap anyways.noway is a 680 $100 more card then a 7950 not even close performance wize
