The price of current Pentium processors is dropping rapidly, which makes it clear that Intel is making way for their new Core 2 series which have clearly shown to perform much much better.

But when purchasing a Core 2 Duo processor, is it best to spend big and purchase a 4MB L2 Cache version? And what kind of overclocking performance can you expect using an after market heatsink? Well that’s what we are here to find out today. That said, the higher-end E6700 is not the only Core 2 Duo processor that we are going to squeeze some extra GHz out of. The bargain basement E6300 will also have its clock speeds re-worked for extra performance.

Using the Core 2 Duo E6300 and E6700 processors with the Thermalright XP-120 heatsink, an ASUS P5W DH Deluxe motherboard and some Corsair PC8500 memory, overclocking was all too easy.
