Hey Tbone, I have a GBT DS5 and it's a fine board and seems very well made.
I also had an MSI K9A2 that died during a bios flash. I never tested either one of these with K8 processors but to be honest I agree with aGeoM.
If I had my choice I'd rather be running on the MSI.

Like I said both of these were only tested with Phenom, but the MSI just seemed to give a little more flexability especially if you aren't afraid to use Beta Bios, plus there is a huge thread started by KTE to help you along and answer alot of questions.

I have absolutly nothing bad to say about the DS5, but if I had it to do over, I would buy another MSI K9A2, plus it's cheaper...
