Safe overclocks on the Q6600?
I'll be getting a Q6600 and there's a possibility I'll also get SLI 8800GTX to go with that. I'm considering overclocking the Q6600 slightly because it can be quite a bottleneck for these cards. Assuming I'm unlucky and get a B3 stepping, what's the highest overclock I could manage while sticking with stock voltages and the stock cooler, not increasing heat production and not decreasing the lifespan? I realize that this is hit and miss to some extent and that different CPUs overclock to different degrees, but what's a safe average?
Would overclocking the FSB to match Q6700 speeds - 2.66GHz - be safe?
Since I'm completely new to this, does overclocking increase power consumption, even if you keep the component at stock voltages?
