A 2x 680 will be more powerful but if you want amd then definately 2x hd 7950 but beware of microstuttering

Microstuttering, the new Nvidia Fanboy reason to avoid AMD. (Replaced "horrible drivers") with a non existent issue atleast for me.

2x 6950s @ 1080p in any game, no stuttering for meh cuz Vsync specially on BF3 ;)

You want to crossfire two 7950's to play vsynced at 1080p? Why?

Tom's did an article a little while back and showed that microstuttering was persistent in lower end cards (below a 6870) and that it was both amd and nvidia that suffered from the phenomenon.

Toms did an artical a little while ago regarding the 78xx series having sacrified quality for performance, atleast tried to lead the readers to beliveing that. When in reality it was a simple driver fix that was indeed fixed by AMD when it came to light.

Regarding microstuttering, if you are only going to go off of one source of information atleast take into consideration that this is all on spreads and charts when in reality microstuttering for the majority of the time only effects eyefinity crossfire users which is a very small catagory. I use two 6950 2GB cards for 1080p gaming and my FHE is superb no matter what sensationalist writing toms has to offer.

Two Sapphire 7950 OC edition cards :) 

I have dual 6970's with a X1100T and I don't have microstuttering or bottlenecking.....hmmm strange.

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

No microstutter here on 480 SLI.
They guy you just commented on uses a 6870 with a 6 core phenom II...


Yes it is more 50/50. I should have said it was the Noobs (and not Nvidia alone) that finds a new excuse to avoid something lol.

I never have microstuttering for any of the 100+ games I play and half or more of them I always run vsync so no tearing either. Now Nvidia has their custom vsync that will pretty much eviscerate the whole microstuttering/tearing debate for them which is a +1. Which is also one of the reasons I am going to be buying a 680 and maybe SLI them by end of the year.

Adaptive v-sync doesn't solve microstuttering, does it? It just turns off v-sync when your framerate drops below 60 and then turns it back on when you hit 60 to prevent tearing.
