A couple of weeks ago, I shared the pain in the bellybutton experience I had with the new ASUS motherboard with the Granite Bay chipset, and the crashing problem related to the ATI 9700 Pro.
So after two weeks of hell, I returned it and purchased the MSI 655 Max. A motherboard with very similar features (Dual Channel Memory, Onboard peripherals, etc.).
So far the MSI has been flawless. Very easy to setup and get running and quite stable. The price was actually about $30 cheaper, and I got a small performance boost over the Intel chipset.
I haven't had any crashes so far, where with the ASUS, I crashed in many different programs on a regular basis.
So far, (two weeks of running the new MB) the MSI 655 Max gets a big thumbs up !
