I recently purchased the Biostar M7VIP motherboard but have been reading nothing but good things about the Epox 8K5A2, and have decided to get that instead. My question is will I need to format my HD again and reinstall the OS and everything? I'm assuming probably not considering both these boards have the KT333 Northbridge and 8235 southbridge which is really what matters. So can anyone give me a definite answer to this?
