I tend not to agree with you here though. For one thing many of the AMD parts are actually clocked higher than the equivalent ones.Also you can get triple core processors for the price of dual core Intel parts which complicates things even further!!
Look at these reviews for example:

The £120 Phenom II X3 720 with DDR2 is as fast or even faster in the games tested than the more expensive Q6700 and Q9300.
Remember that the Intel processors which are faster actually cost much more than the Phenom II X3 720 and 710 for example.
Check the prices for the processors including a heatsink and you will see why.
Also overclocking is not guaranteed with any processor. It depends on the other components in your PC too. For instance the Phenom II X3 720 has an unlocked multiplier which means it can overclock well with even a cheaper motherboard!
