I just got the M59. From what Ive read at Anandtech when they compared it to the most recent Foxconn 590 mobo was favorable. It's future proofed for some of Nvidia's upcoming GPU setups. I have had a chance to fire mine up yet as Im still waiting for my PSU.
For the moment Im running a Radeon X1900XT until the GTX prices come down and then I may consider SLI.
Just as an update:
Got the board.
Very nice and easy to work with.
BIOS is easy to navigate.
This was my first build and I had absolutely no issues with any of my components.
Colors are a little gaudy but very functional.
Only issue I have is with onboard audio. It isnt working. I used the latest drivers but still issues.I think its something im doing though.
I recommend it.
I have to upgrade BIOS to the F4 version.
Thanks for all the help, I should be getting mine in a few days, looking forward to installing it. I've been without a desktop for a month or two now, and I'm an avid gamer so I've been very bored.
