First, the theoretical numbers:
score = (core clock * (texture units + pixel shaders)/2 + mem clock * (bus width/16)) / 500
for example:
x1900xtx = (650 * (16+48)/2 + 775 * (256/16)) / 500 = 66.4
7800gtx512 = ((550 * 24) + 850 * (256/16)) / 500 = 52.4
x850xtpe = ((540 * 16) + 590 * (256/16)) / 500 = 36.16
6600gt = ((500 * 8) + 500 * (128/16)) / 500 = 16
For SLI, simply multiply single card score * 1.9 (edited from 2.0)
Then, run the FEAR video stress test at 1280x960, 4xAA, 8xAF, max settings, (*edit: disable soft shadows) and report your average fps. Compare the theoretical score with the actual result in FEAR.
My numbers:
x1900xtx = (650 * (16+48)/2 + 775 * (256/16)) / 500 = 66.4
Actual fps = 68
x800gto = (580 * 16 + 590 * (256/16)) / 500 = 37.44
Actual fps = 39
score = (core clock * (texture units + pixel shaders)/2 + mem clock * (bus width/16)) / 500
