I have one of those, and...
It's not stable. I don't know if it's the mobo, cpu, memory, or what, but something not right. Components that worked just fine in my previous computer (floppy drive, cdrom, dvd-rw) don't work right. And it seems to be stable, passes various stress tests, but then it crashes sometimes, with either a BSOD or just weird behavior such as every time I open an MSIE browser, it immediately exits with an error reporting message.
Backing memory off to 2T timings seemed to help some, but the memory passed 24 hours of memtest86 and still crashes in windows. I can't figure out what's wrong, cpu, memory, or mobo.
Also, the voltage and temp monitoring doesn't work quite right with this MSI board for a lot of people. It reads high or low for many people, making it tough to tell what's really going on especially when faced with problems. If the cpu temp reads high and the computer crashes, is the temp actually that high or are you just chasing down a dead end trying to cool down the cpu?
Anyhow, that's what I've been faced with when using this mobo. If I had to do it again, I'd go with ABIT or ASUS.
What I suggest doing is trying to sell off what you have including the video card, and going with a socket 939 ASUS board with pci express. I'm close to doing this myself due to the instability, and since I don't want to swap out every single part one at a time and if I have to go to a new mobo, I may as well go to pci-e on the vid slot, and that means a new vid card too.
A last comment regarding this MSI board - there seems to be stability issues with it and the dual core cpus. The bios updates haven't come all that regularly from MSI and it seems like either they can't fix it, or they aren't all that interested in fixing it. Either way, I'd go with ASUS or ABIT.
IMHO.
