no what is FSB? what the heck does FSB have to do with anything?
Unless you are getting a hell of a deal the Q6600 is not worth it.
I swear some of you are just getting off the newbie bus...
Here it is, short and to the point.
Motherboards that support 1066 FSB, and don't already have a Q6600 would be ill-advised to not upgrade to a Q6600; if their usage determined the need for a quad.
The Kentsfield's are the pennacle of the 775 chipset @ 1066.
