Intel Core2 Quad Q9400 

Released July, 2008
  • 2.66 GHz
  • Quad core
6.7 Out of 10

When it comes to benchmarks, the overclocked Intel Core 2 Quad Q9400 processor was able to complete the benchmark just as fast as the Intel Core i7 940 processor, which is wicked fast.

As you can see above, the ASUS P5E3 Deluxe motherboard FSB runs at 334MHz, so right out of the box the FSB is a little higher than one may have expected.
