I'm looking to upgrade my cpu/motherboard. Currently i'm using an intel Q6700 with an asus p5Q-e mobo. The cpu I have my eye on is the phenom II x4 965 black edition, however I don't plan to overclock it and it seems that the product was designed for overclockers, so i'm worried I won't see much of an upgrade without doing so. I'm upgrading because I recently upgraded my gpu to a radeon hd 6870, but i'm not getting the fps I should be, and i've been told it's probably bottlenecking at the cpu. So basically what i'm asking is will a see a noticeable performance upgrade with the 965 over the Q6700 without overclocking, and what mid-priced mobo will go well with it. (Keep in mind that I plan to crossfire 6870s in the near future, so the board has to be crossfire compatible).
