2700k EVGA GTX 580

Every chip is different.
What are your voltages and load temperatures on your 2700K?

Also curious as to the voltage necessary to run your 2700k @ 4.8... 1.45v - 1.5v tends to be the safe threshold for those SB chips.

4.8ghz for a 2700K is a good clock you could probably take it to 5.0ghz, but what for?, it's already doing whatever you need.

Your 580GTX clocked to 2200 core clock, means you GPU would be running at 1100mhz, what voltage are you running that clock at?

I have yet to come across anything that my 2600 non-k doesn't chew up and spit out at the stock speed of 3.4ghz. The only thing that really benefits from these CPUs at higher clock speeds are benchmarks, and they're typically synthetic anyway. We all overclock as we can and when we can, but other than putting the stats in your signature...I'm not sure the difference in speed would benefit you in any real-world application.

Especially with it's hyper threading capabilities.

Im working around with the numbers also mIM adding SLI 680's anmd using my 580 as a physx card next month when my stuff comes in
