I have experience with your situation. I spent several months trying to make 3 way crossfire worth it. As of a month and a half ago, it was very unstable and, often times, no benefit at all. My system was portrait @ 3860-1920. The same is true for quad SLI @ the moment with 690's though, if they ever get proper per card utilization, that could change. Probably , go with the 3770k or 3570k for PCI-E 3.0 ,so get the Sniper
