Updated score with a oc i tried today. I just bumped the core +85 to make my core default 1000 from 915mhz and it boosted to 1228.1mhz. Was running on 314.22 drivers still which i know arnt the best for this benchmark but still. My cpu remains a i5 3570k at 4ghz.
It completed the run so presume thats good enough. But i will point out at the end i did gpuz render test and trying to move the render box about i had delays of it moving for a sec or two after i released the mouse. Was fine after i clicked on default on precision x to revert to normal speeds. So i duno, make that of what you will.
Skeeter could you check to see if you have your integrated graphics turned on please. The screenshot is showing HD4000.
Thanks
