I have the same board, and you'll have no problem as long as you have good RAM and a decent CPU cooler.
I'm running a E6750 @3.66 WITHOUT ANY EFFORT!!!!

The Asus P5K they use is similar enough to get you started and if you don't tinker with the voltages this is more than enough. BTW JumperFree Configuration is the equivalent of Extreme Tweaker on the Maximus II.
Also I suggest Core Temp to monitor CPU temps and the PC Probe II (included w/software) has proven good for MB/NB temps.
