WEll since you opened the option to go with AMD and switch mobo and everything, why are you looking at socket 775, you would be better off to go with 1156 and grab the pentium for 1156, or grab an i3, but the 1156 pentium is basically the same price as e6600.
I'm looking at this not for a new build but to replace my e5200 after I sell it. So I already have the mobo and basically the whole set up and will just use this (if I get it) as an upgrade.
I don't own an 1156 mobo but if my video editing gets to a point that my Q9400 @ 3.5 Ghz starts to bog down I'll probably build a new rig then, and probably will not go with Intel.
I see your point about the i3 but I don't want to buy an 1156 mobo.
