I have finally a 975X board running, tested first with a 670 and now with a 955EE Presler. I have the predecessor board, the 955XBK, as well, and a direct comparison shows that the 975X is in bandwidth around 5% better, they also have optimized the layout, and I even found an "oc debug" jumper (the meaning is still eluding me). The 975XBX offers voltage adjustments for: - Memory - Vcore - Memory controller - Front-side-bus The FSB frequency can be adjusted 30% upward. The board runs the 670 aircooled at 4.5 GHz 100% stable since around 3 days with 2 FAH instances. And that is with just a little bump of 0.1 volt. At firstname.lastname@example.org GHz this 975X system delivers an amazing 710 points per day when running 2 x QMD. Crossfire is working w/o a hitch. However, I am using 2 lowly 1300 pro, and the impact in 3DMark 2005 is negligible. The 975XBX looks very good so far, considering that Intel boards are usually 10% to 15% cheaper than comparable products from Asus or Gigabyte.
