Just bought my mac mini quad core yesterday... Gotta say it's blazing fast so far. Given anything would seem blazing fast going from my ancient Mac Pro circa 2004... But no regrets so far on the Integrated HD 4000 gfx. Will put it to the test soon, but i don't play games on my mac. So as long as it can handle some light 3D filter work in after effects and avid i'm happy.
