I've got one 7870 OC in my PC at the moment, I was wondering if anyone here has any experience with 7870s in Crossfire, and what sort of performance I should be getting out of it (mainly BF3). I find at the moment at 1920x1080 on the Medium preset I'm getting around 60fps in multiplayer, but I want to aim for high/ultra.
Generally when you drop 2 cards into xFire / SLI you get a little short of double the performance. My 560ti's in SLI put me around 54fps on Ultra at 1080, so I would expect quite a bit higher than that with those cards and your proc.
Actually I would say that BF3 is one of the most optimized games out there.It fully utilizes everything your PC has to offer.
I agree with itzdanielp.With a 7870 crossfire you should be able to max out BF3 at 1080p and maintain a 60fps average.If I had to make a guess on the exact fps you would get I would say somewhere in the range of 60-80fps.
just ordered one from newegg...i was expecting a little more performance than what you just mentioned : / benchmarks had set it running at over 60fps on high
Well I was messing around with the settings and on the Ultra preset (minus AA deferred) I was getting 60+ FPS. Don't know whether it was the map size (Metro) compared to some of the really open maps or what. It's sort of tempting to save up and get another one and just blast through the FPS, and continue to do so for the next few years, but whether or not I can justify $359 for it is another question... All my other games run very well, just BF3 and Arma II.
