I don't think you'll be able to get past the 10k limit even if you have the new experimental CPU Intel people are working on..........having a better, like a quad, (atleast by what I've understood) will give you better performance, not more men.

I myself have an AMD dual-core (2.2 Ghz)
Same here, and I love that thing, when I was buying it, I wasn't so sure, it was the Intel Core2 Duo or AMD Dual Core, and I sure am glad I chose the latter.
