I saw this on Overclockers and burst out laughing, I'm supprised Overclockers even aloud the review to be posted

Intel Core i7 975 3.33Ghz (Nehalem) Extreme Edition (Socket LGA1366) - Retail + World In Conflict PC Game
'Sold my car to pay for this and what can I say: it was worth it! Overclocked it to a incredible 3.7Ghz simply by changing a few numbers in the BIOS.
I've teamed it with 2 6600GTs in SLI (and my spare GTX 295 for PhysX) and I can play Crysis at my monitor's native resolution (800x600) with (almost) all effects turned on high and it's just breathtaking!
Highly recommended.'
