It's actually not recommended, because there's no real-world performance difference from enabling and disabling Speedstep. There's an idle issue with the 2600k chips, and disabling C3/C6 states for some have fixed that issue. However, disabling C1/EIST is not recommended, and not optimal. The only difference is rather than your core idling at 1.6Ghz to save energy and reduce heat, it's idling at 4.8Ghz which is ridiculous because you're wasting energy and causing unnecessary heat when you're just doing nothing but browsing the internet.

The switching happens in microseconds. I know it looks like it may take a while to switch when you view CPU-z, but the actual switching is happening at a ridiculous rate.
I always OC with the power savings on. You are just burning power for no good reason when you disable them. Back in the day you had to disable them for stability, but not so much anymore.
