how is it far better?I own both.
I say e8400, FAR BETTER!
As for future proof? Thats all hear say I will wait to see some quad advantage programs first before ever buying a quad again.
I PERSONALLY will not make that mistake again.
if your going to upgrade to a 45nm quad later on, go ahead
but a q6600 is great for multitasking and will last your computer longer
