Except that you haven't posted facts.
"There are plenty of benches out there that state quads are faster per clock cycle. Windows and directx will not have to change anything"
Wrong. DirectX is not capable of multithreaded interfaces. And Windows does not load balance for you or the app, the APP must do the work to spread itself across the multiple cores available.
Most of the higher resolutions, the q6600 pulls away even at only 3.6ghz.
Wrong. The Q6600, at higher resolutions, matched the E8400 when it became GPU bound.
"UT3 doesn't use four cores, go and google it"
Wrong. Sweeney himself said it does.
It is YOU who are pushing your opinions onto others as if they were fact, when instead you are doing it for no other reason than to push quad cores due to your own bias.
Here are the facts:
You have multiple benchmark sites telling you that duals are better for gaming.
You have multiple game developers telling you that duals are better for gamin.
You have multiple cases of people claiming "multitasking" like AV, IM and the like necessitate a quad -- when faced with the reality that, no, those services take up less than 1/10th of 1% of your CPU time while running.
I currently own, use and overclock a penryn quad at 3.6Ghz, and my very last processor was a penryn dual at 4.2Ghz. And using the exact same motherboard, ram, video cards, drivers and operating system, games went faster on the dual core without question or fail.
Those are the facts, your suppositions and opinions are not.
