Wow this thing works the shitz out of your card....looks freakin awesome though!
Here is what you do to set up the bench.
Install the small program and then fire it up, Make the setings 1680x1050 and set the tessalation to HIGH...these are the max settings for this.
click run, then once your in the cave push F4 and then press ENTER, this will start the benchmark. Post a screenie as im interested on what some of you do with other cards with this very high end DX11 being used.....
Here is my run, wasnt shooting for the moon just a normal everyday settings run.
