I have the 6 core with d500s. Ive been looking at the E5-1660v2 as a replacement. Mostly for it's higher clock speed for photoshop/lightroom and games in bootcamp. Also because there are cheap used chips available that I can try. It is a small bump in clock speed but I have seen good single core benchmarks. As for my needs, would be the best option...vs an 8 core chip? Has anyone here swapped the xeon in your trashcan? Cheers!
