I had been planning on building a new rig with a Q6600 ever since I heard of the price cuts till very recently. After thinking on it for quite a while I realized that I mostly just do gaming, listen to music, surf the net, and watch movies. For these tasks, right now anyway, a quad core is really not necessary. For these tasks an E6750 or E6850 would be better because I would be able to get a higher clock out of them. So what it comes down to is that a quad core would be cool, but for what I use a pc for the dual cores would for sure be a better pick atm.
