OK... Here's an interesting update for my fellow K9A2 CF users...
I'm sure those of you who had bothered to check the CPU support tab on MSI's website in the past would have noticed two tabs: one for v1.X, one for v2.X, with the v1.X only listing CPUs up to 95W. This is the case no longer, as the CPU Compatibility tab now only has one list which includes all AMD socket AM2, AM2+, and AM3 CPUs, including the 125W models. How is it possible suddenly after over a year of no 125W support? I had to find out...
I called MSI just a short while ago to verify the 125W CPU support. Seeing as 125W CPUs aren't exactly new (Windsor and Agena anyone?) and the fact that when I last looked (only two weeks ago) the separate listings for each version were present on the website, I had to double check the list to be certain there wasn't some sort of error. Sure enough, the tech informed me that the v1.X board simply hadn't been tested thoroughly for compatibility with 125W CPUs. He went on to state that MSI recently tested 125W CPU's on both versions of the motherboard and was able to confirm that both now fully support all 125W CPU models. They now list even the new Phenom II 940 as a supported CPU!
So, for anyone who has been considering an upgrade, or possibly even a new build, this recent change in CPU support may in fact be the v1.X's saving grace. Personally, I'll be impatiently waiting for the release of the new AM3 Phenom II's on the horizon.
Edit: Should have included a link to the new CPU Support List: http://www.msi.com/index.php?func=prodcpu2&prod_no=1333&maincat_no=1&orderby=wattage ASC#menu
