Hey BigD, we talked a couple of weeks ago of the virtues of your x1800 over my 7900GT, well swapped my 7900GT for the 256MB x1800XT and pocketed some cash, only got it today so just did my first run on it on stock cooling (check specs/siggie), am about 140 points short of the 7900GT but as it's only my first run it aint bad and with no flash, am at 1.475V on the GPU (am a bit shaky about goin higher?), any tips would be appreciated, sorry to temporarily hijack Marks thread, will start a new one tomorrow for advice!
