Guys you need to wait for couple of days for the prices to lower to Intel's MSRP.
The Q6600 has already began the drop going from $480 to $455 on newegg
Newegg.com - Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775 Processor - Retail
And its $399 at ZipZoomFly right now.

According to that review ^^ E6750 can be overclocked to 3.6GHz with stock cooler. I don't think you can easily overclock E6300 to that speed.....

I can grab a e6420 or even a e6320 and OC it to the same speeds for $50-$100 less.
