I'm thinking about moving to Intel, and have been looking at a 65nm E6750 (2.66ghz) or a 45nm E6550(2.33ghz). The 6750 is £117 and the 6550 is £104. Question is, is it better to get the slightly slower 45nm or go for the 65nm faster chip. I'll be pairing it with an Asus P5K and 2GB of Corsair XMS2. Cheers!
