Which Processor??? More Speed VS. More Cores?

In this case, I would probably go with the Quad Core. Sure, the Hex Core is slightly slower, but it does have more cores than the Quad Core, which should make it more efficient in rendering video and other things like that. Unfortunately, I don't think many applications, including After Effects, can take full advantage of a Hex Core. More and more programs, especially high end games and rendering programs, are beginning to take advantage of Quad Cores to increase speed and efficiency. Correct me if I am wrong, but I would go with the 975 Quad Core @ 3.60GHz and then save the money to get better cooling or a strong GPU or something.
