That will be a bit tricky. The computer is broken and I was getting parts to fix it, which included a motherboard and CPU. So I got the same motherboard, but a better CPU to give it a little boost. Would it be possible if you could find out if a BIOS Update would be needed in order to use an AMD Phenom II X4 850 on it? Also, what would happen if I installed the CPU chip without the update?
