Push your new 580 with this demo. Best graphic effects I have ever seen.
This graphic demo from Andromedia has some of the best visual effects I have ever seen. Forget DX11 and check out what opengl is going here. Wow ! It will bring my 480 to its knees at times but man you guys with good cards have got to check this one out. It starts out a little slow.
