I have had no problems with the Jetway 663AS pro mobo that I did not inflict upon myself. Nor for that matter have I had a problem with the nVidia GeForce 2 MX sold under a Jetway logo
The board doesn't seem to allow multiplier o/c ing, but I can get the Graphics card stable and cool within 5MHz of its max capabilities for Core Clock and Memory Clock. I have only had problems when I flashed the BIOs, and it was my own fault. Do some research before you slag off Jetway!!!
