http://i.imgur.com/zphlK.png So my score is 2331 points (46 FPS, 130000ms) I was comparing them to online scores of people with the same card, and they are pulling 20-50 frames more than me... So I just did some bench mark tests for my OC 560 GTX TI here are my settings. Core Voltage is 1070 Core Clock is 980 Shader Clock is 1960 Memory Clock is 2200 Fan speed on auto. I have a i5-2500k OC to 4.5 ghz as well.
What kind of 3dMark11 score do you have? I have used Kombuster before and my sli score was lower than single card scores. I dont think it is a very reliable benchmark.
