Well yeah, if you are DEFINITELY not going to overclock, and you do not want to spend an extra 500 bucks on a mobo and the CPU, then it makes sense for you to get the fx-62, seeing as how you can keep the rest of your stuff. However, I do want to say that Intel is outdoing AMD in their higher-end stuff, and that you might be sorry you did not get an Intel compatible motherboard.
