If your main focus is gaming, get the i5-2500k. It'll save you about $100 since games don't use the hyper-threading. Like WR2 said, the P8P67 Pro would be plenty. Also consider the ASRock P67 Extreme4. Both do x8/x8 SLI. For a stable mid-4s overclock, look at the Scythe Mugen 2. Best cooler for that price.
