The 10980XE has some head room to OC unlike previous HEDT from Intel. You can get it to 5.1Ghz with standard water cooling. THis tells me I can push the 4.8Ghz Turbo Boost 3.0 to 5Ghz. I thinki 4.8Ghz is faster then a 5Ghz 9900k single core. Now you got 18 of those babies.. and 36 threads and what not.
