GOD! I hope santa is good t me this year, if so, i'll be calling your score with an i7 920 & HD5870! (ofcourse i'll be OC'ing them too)
3DMark loves Nvidia, and loves Nvidia in SLI even MORE. I only pull 17543 on Vantage with a 920 @4GHz and a stock clocked 5870.
(2) GTX 275's will boink a single 5870. Zoom Zoom.
