I have an asus M2n sli Deluxe motherboard, running an AMD athlon X2 6400 2.21 GHz, and I was thinking about switching it out for a newer faster cpu. This is one thing I have never really touched before, I have heard differing opinions about what is involved, would I need a different motherboard to run a newer cpu, even if it is the same socket type, would I need to reinstall windows, I have also heard that. Please let me know.
