imo keep the Kuhler and get an i7 2600k
but, stock is fine for non 'k' cpu
Well the 2600 has some features the 2600k does not. The K processors do not support Intel TXT, Intel VT-d or vPro. And my assumption is that if I am running VMs on this I will not need/want to overclock. Besides I already have the 2600 in another computer.
Also are you sure that the stock CPU cooler will be ok for 24/7 folding? I'm kinda picky about the temps I get. I'm probably just crazy.
