The new software from Nvidia fixes microstutter and tearing. Yes micro stutter is real, yes tearing is real. Most of the time you will NOT notice micro stuttering. SLI has its issues and benefits, but I think I will do it with my 680 when I need to. Both cards you have listed are excellent, but they 79070 just got a price reduction on newegg maybe that over a 7950. Also I really like my 680, but any of the cards mentioned are great! The next gen consoles PS3 and XBOX 720, are supposedly using a 6670 and 7670 (which is a 6670 re labeled). So those are not due out for a while and 7950s, 7970s, 680s, 7990, 690 are all going to rock both those consoles and games for a long time! Maybe wait until the new Nvidia cards come out prices are changing like crazy. Try and wait see which has the best FPS/$ ratio. Dont be afraid of either AMD or Nvidia, toms is really good about not being biased, don't listen to others. Hope this helps MAN OF KRYPTON
