ummm.... well in the first place you can OC an e6600 from 2.4 up to around 3.5-3.8ish on stock cooling, i would suggest getting something HUGE for the 8800GTX, probably something with an external DC pump because your going to need it, but for the CPU i would get JUST this thing it is REALLY sick for OCing your CPU. it doesn't let your computer turn on until the unit chills the cpu to -10 degrees Celsius. but i dunno about the 8800GTX, if you got this and left the GTX stock it will still run just fine and you will be able to OC the e6600 up to INSANE speeds of like 4.0-4.2ish.
