Encoding and 3D manipulation benchmarks have the quad-core CPU clearly ahead, while general usage and gaming benchmarks mostly favor the higher clocked dual-core E6850. So, which do you choose?

If you're strictly building a gaming box, you'll get more performance out of the dual-core E6850. However, if you do any encoding or 3D rendering at all, the quad-core Q6600 is a better buy. Our pick is the Q6600 and if you want to make up the performance difference you can always overclock to E6850 speeds, but the chip only makes sense if you're running apps that can take advantage of four cores. As the chart above illustrates, those applications are almost exclusively limited to video encoding and 3D rendering."

According to that explanation, if you overclock a Q6600 to 3.0ghz you will still have the performance of a E6850 but quad core. So in my mind wouldn't it be smarter to buy the Q6600 for the same price as the E6850 and overclock it to 3.0ghz+ which should be easy on air. And in the end have two extra cores. Or am I missing something?
