it does with intel. it doesnt really with amd.
with intel chips (help me out here intel people) the fsb can make a tremendous difference in performance, especially if you overclock.
wow that e6850 looks really appealing. I will almost definately upgrade to that, then with an OC i don't think this computer will be behind for a while, since im getting my 8800gts next week, and maybe ill use the step up program to go up to a gtx later on.
I'll guess I will follow what you guys said here and wait then anyway there is no DX10 game out yet, so I'm in no hurry at all beside price on other part should drop more by the time those CPU comes out.
One last thing should I go with:
E6750, E6850 or the Q6600, I will be mostly gaming.
Don't go for the E6850, when the Q6600 is the same price. And don't go for the E6750, when the E6550, can easily overclock pass that, for cheaper. So it's either the E6550 or Q6600.
