Core i7 overclocked to 4.2GHz

Because Core i7 Extreme has multiplier unlocked, so overclockers can easily OC to 4.2GHz by pulling up the multiplier. But like Phenom, the bus speed can not boost a lot. So we’d better drop our thought, they are not Core 2 anymore, so we may not have chance to see 500MHz+ bus speed.

If you read the everest benchmark chart and 3Dmark Vantage, the performance looks quite impressive.
