That's a good Mobo, no need to switch now, just upgrade our CPU. You can find a good bulldozer chip for under $200. Honestly there is no reason to switch to intel and change Mobo given what you have. Bulldozer might be a letdown, but you already have a good mobo for it, and can upgrade your CPU easily, and also the Bulldozer series do overclock quite well. The best thing for you to do would be to upgrade our CPU and then upgrade your CPU/Mobo (and probably GPU as well) in a year and half/2years with the release of Haswel. I'm happy with my Sandy Bridge CPU, and going for the i5 3750K wouldn't be bad by any means, but it's just totally unessesarry given what you have.
