Overall it is a good increase but the question is how big. http://www.guru3d.com/articles_pages/geforce_gtx_670_2_... m 0 l jrmurph3 November 13, 2012 2:29:31 AM There is a major increase in performance in theory. Like ss202sl says, it depends on the game, settings, etc. Do expect more heat and more power consumption. Make sure you have a decent PSU. m 0 l Related resources Gtx 770 2gb vs 4gb 1 card and SLI - Forum P5N-E SLI only running video card at x1 not x16.

Maybe a bit more if you are going to overclock and just so your not stressing it too much. m 0 l cats_Paw a b U Graphics card November 13, 2012 9:24:09 AM Id go for 800W or more for 670 SLI myself, basicly to have PSu not run at full, and to have even then some room for expanding. And definitly a good brand (XFX, enermax, thermaltake, Corsair, seasonic...). m 0 l ProVisionOman November 13, 2012 9:33:48 AM If you're going to overclock go with the corsair 850w. m 0 l jrmurph3 November 14, 2012 8:44:45 PM Yes, definitely go with a PSU that allows you to expand. You never know when you feel like adding more to your PC and when you'll need that extra juice. Always plan ahead, though! m 0 l Can't find your answer ? Ask !
