I recently had the opportunity to borrow a Quad Core Intel "Kentsfield" processor & take it for a drive in my Hack Pro! I would have liked to have overclocked it as the multiplyer on these is unlocked which means with the right cooling you could be looking at some great speed without the usual associated fsb overclock problems, however the processors owner was not to keen on me melting half a grands worth silicon. Shame!
The processor was fully recognised, just look at that L2 cache below! It ran like a knife through butter. I really need want one of these. I will put some tests up soon.
