The M3A78-T performed slightly better in a couple of cases than the new M3A79-T Deluxe we are reviewing here - but the difference tended to be minor. The new SB750 southbridge brings the new "ACC" (Advanced Clock Calibration) control that is supposed to improve overclocking, but frankly, it did not do much for me. The gaming performance of the board was excellent at lower resolutions; combined with an ATI Radeon HD 4850 I believe this board would make a decent gaming rig. It certainly has enough GPU slots :) The Asus M3A79-T Deluxe is an excellent motherboard, with decent overclocking capabilities, whose performance is slighly hobbled by the sub-standard memory performance of Phenom processors.
