I'm having trouble deciding between getting an e8600 or a q9550. I'm upgrading from my e6400 and money isn't really an issue as i can get either for a reasonable price. I had a look a different benchmark charts and it shows that the q9550 out-performs the e8600 in most of them. However i've seen and heard that the e8600 can be overclocked to very high settings and can therefore out-perform the q9550 even when the q9550 is overclock itself. Anyone have any advice please?
Personally I wouldn't pay over $100 for any dual core, the E8XXX series has been horribly priced ever since I7/Phenom II released and C2Q prices dropped.
If it isn't clear, my vote is for the quad. 2 more cores will provide a lot more processing power than a few hundred extra mhz of overclocking head room. Quad will last longer before you need to upgrade again as well.
