So I Owned A Mid 2010 iMac Basemodel and It broke 3 times so I ended up getting the Mid 2011 As A Replacement. I Do game, and before you go saying WHY WOULD YOU GAME ON A MAC!?, Its because I Simply got the iMac because I Wanted a Mac, And Felt it would be better in the long run than building a PC, and boy was I right, well sorta, the Mid 2010 WAS HORRIBLE at gaming, But I Am here to tell you that Apple Really has proved the Fanboy's wrong about macs not being able to game, the Mid 2011 iMac I Would say from Personal Experience, is about 75% BETTER than the Mid 2010 (Last Generation) iMac in everything! So Here are some Benchmark Scores and FPS I Am Getting in a couple games/Programs. Keep In Mind im running Windows 7 Home Premium SP1 with bootcamp 3.3 (I Need to update to 4.0), and the Catalyst 12.2 uncertified Drivers with the MBP 6750m ULTIMATE overclock. Windows 7 Assessment Score: Mid 2011 iMac: 5.9 (HDD is limited this) Mid 2010 iMac: 5.7 (GPU/HDD Limited) Battlefield 3: Mid 2011 iMac: 50+ FPS (Medium/High Settings 720p) Mid 2010 iMac: 30+ FPS (Medium 720p) GTA IV: Mid 2011 iMac: 45+ FPS (Medium/High Settings 1080p) Mid 2010 iMac: 30+ FPS (Medium/Low Settings 720p) Flight Simulator X (FSX): Mid 2011 iMac: 45+ FPS (On Ground) 60+ FPS (In Air) (Maxed w/ REX 1080p) Mid 2010 iMac: 30+ FPS (On Ground) 50+ FPS (In Air) (High w/ REX 1080p) Halo 2 Vista Version (DX10): Mid 2011 iMac: 60+ FPS (Locked) (Maxed 1080p) Mid 2011 iMac: 48+ FPS (Maxed 1080p) Portal 2: Mid 2011 iMac: 145+ FPS (Maxed 1080p) Mid 2010 iMac: 90+ FPS (Maxed 1080p) Passmark Performance Test 7 64bit: Mid 2011 iMac: Total Score: 1678.3 Mid 2010 iMac: Total Score: 1165.4 I Can Definitely Say that the iMac can be used for gaming Extremely Well as I Am doing it right now. I Don't Recommend the 27" For Gaming Because of its Resolution but the Best iMac For Gaming Would be the Top 21.5", though the Baseline like I Have is doing it extremely Well. I Thought I Would Share this!
