Question: I'm replacing my AMD CPU with a similar but not exactly the
identical one. Older one is 2.3GHZ, newer one is 2.8GHz, for example.

I have no problem with the mechanics of replacing the CPU, but I'm
wondering if any drivers, BIOS, etc need replacing.

I checked the ASUS site, and there is no newer BIOS than the one I
already have. Likewise chipset drivers are up to date in my system.

What else might I have to do when I replace the CPU?

Many thanks!

Jack
