I'm thinking of buying a new mobo with a socket for an Intel cpu, that supports crossfire. Most likely the ASRock Z87 extreme4. The cpu is gonna be an i7 4770K. I've already got one Sapphire 7970 Vapor-x graphics card installed, and am thinking of buying another one to give it some company.

I've read a post about somebody complaining of having major issues(like major struttering, fps drops, crashes) with crossfire-ing AMD cards on an Intel socket mobo. I really don't want this happening to me after I'd spend 800€ for the whole mobo, cpu and gpu.

I couldn't find any other posts of people having problems with Intel/AMD compatibility. If anybody has experience with this, please share them here. Also any reviews, posts will definately help.

This person was probably experiencing playing crossfire in new games or old games without support yet. Support for cf is definitely getting better, and so is scaling. You would get approx. double fps in most games. There's nothing wrong with intel and cf together, sounds like an amd fanboy looking for attention to me lol, or he doesn't know how to update his drivers. You'll be fine, go for it! Just make sure the PSU has enough juice for all that. Something like 800w or more.

I just find it weird that somebody had such bad luck with his Intel/AMD system. Must have spent lots of money before he figured it out. And I've read a couple of posts saying that there's a lot of micro strutter on some games such as BF3. I'm planning on playing BF4 a lot when it comes out. I guess it spooked me a bit.

Crossfiring AMD cards w/an Intel cpu/socket will not cause you problems. W/out any technical details, an AMD or Intel cpu has no real bearing on how an AMD or nVidia gpu perform on the same platform.

Any stuttering of an xfire system would be caused by, up until recently, AMD's horrible driver problems for xfire. They've since fixed a lot of the issues, but you will still never get rid of microstuttering. Having 2 cards work together, nvidia or amd, produces microstuttering and dropped frames and you won't get full use of both cards (maybe 100% of first card and 70-80% of 2nd card).

You should have no problems getting a second 7970 to work in your system.

The HD 6000 series was known for microstuttering, and Crossfire in general has had some problems in that area. AMD are now in the process of fixing the problem via driver updates. They've already pretty much fixed it for single-monitors DX11, in a few months they'll also support DX9 and multiple monitors with the fix (called frame pacing).

Besides, he was using 6950s unlocked to 6970s. Not exactly supported.
