I used to have 6850s in crossfire and the performance was about the same that the GTX 580 that I got after. I was not experiencing micro stutter or tearing or whatever. The only annoyance is that older games arent supported (but a single 6870 will max them out so it's not a big deal) and you have to wait a few days/weeks before AMD release a xfire profile when new games comes out.

 

I'd say go for the 6870s, they are really, really powerful.

 

For reference, two 6850s where giving me 60-90 fps in BF3 at ultra with the AA at 2x. AA at 4x would give me micro stutter due to the limited VRAM.

^^ This, though I haven't really run into VRAM problems at 2560x1440 myself. Just see for yourself.

And micro-stuttering is real, but it's not that bad. When running around 30 FPS on 2 cards, it may feel more like 24 FPS or so, but above that, it's not a problem.

Waiting for cf profiles can be annoying, but heck, the 6870 isn't that far from 6950 in the first place.

Another vote for the crossfire 6870s. I've had nothing but good experiences with crossfire, actually. Also, if you use Radeon Pro, you can get rid of any microstutter. The performance of 2 6870s is going to be much higher than 1 6950. depending on whether you overclock.

Yeah, I can confirm that. Wasnt that much of an issue though, because there arent a lot of game in which you will only have 30-40 fps.

 

 

As for the VRAM problem, it only happened to me in BF3 with the AA at 4x. Everything else was fine, IIRC.

Stock 6870s in xfire will destroy a stock GTX 580, thus a 6950.

Are those 6870's you're going to trade for 1 GB or 2 GB? 2 GB will be better in my opinion, since you're playing at 1080p.
