I currently have a 2,66 GHz Core 2 Duo MacBook Pro from 2009, so the Mini should be at least triple the speed (hope this translates to real world). As for the graphics, Starcraft 2 and Diablo 3 both seem to run okay on low with the HD 3000, so they should run just fine with the HD 4000 on low even on 1440p I think, and for everything else, there's my PS3. I don't want to wait for a new Thunderbolt Display as it's probably not a day and night difference to the current one. Now the only thing I don't know is the CPU. Many said the 2,6 GHz chip is worth it. Problem is, first, both chips cost exactly the same according to Intel, so it would be basically gifting money to Apple, and second, is there any worthy real world difference in 1080p video or 36 MP RAW photo editing?
