I've got 144hz monitors, 3 of them, and on all 3 or a single one in AH, I'll get 144 maxed out with both a 3820 and 3930k cpu with 780 gtx cards either single or SLI. SLI doesn't make a massive improvement. I do have the reflections turned down a little, as when it gets hectic over tank town say, with tanks/smoke and lots of cons, if reflections are maxed out, I can drop into the 30 or 40's still.....reflections are a killer to even fast PC's on max. On mid level settings, I still will drop to maybe 100, but rarely if ever under that.
