Well I have 2 of the Intel 120 SSDS going in here shortly.
If you just want to clock the Quad it has been verified by Intel to hit at least 3.7 Gigs. I have gotten mine to 3.4 without additional cooling.
So I would say with direct AC 4.0+ Gigs would be a safe assuption.
If you guys have any particular benchmarks you would like to see please feel free to drop me a line.
