Actually the e8400 beats the Q6600 on almost every test accept video and audio encoding/decoding. Programs just aren't ready yet for quad core computing... and softwares are not even fully taking advantage of dual cores until recently.
Dual core will be plenty for the next 1-2 years. A quad core will probably be better suited for years and years down the road. E8400 = Shorter Term. Q6600 = Longer Term. Your choice.but my personal openion is to go for e8400(price and performence)wise and for gaming cause
q-How much of a difference will you see on the E8400 vs a quad?
a-You'll see a large difference when encoding videos.thast all
and here is a cpu comparison chart
