I got it on sale and found it to be quite the system hog. Granted I'm running 3 screens. I've got an i5-2500K overclocked and running a ATI 7950. With some time and some tuning, I will try it out
Tried it out last night. Absolutely maxed out the graphic settings at 2560x1600. The advantages of having two GTX 780s in SLI.
I wasn't all that impressed with the graphics though. Don't get me wrong, they're good and I like the active aero on the Pagani Huayra but I think the latest console titles beat it in terms of graphics.
Not really convinced on the physics either. The grip seems a bit wonky.
