Hey guys, I recently built a budget gaming rig back in April. I have the FX 6100 at stock speeds and the GTX 660 SC. In the future I would like to add another GTX 660. From what I have read on here it looks like that CPU will really bottleneck my performance. My question is, if I can crank this CPU to 4.3-4.5ghz will that be sufficient enough to support dual GTX 660's in SLI?
