I purchased my current Mac Mini, the mid version with AMD graphics, the week it came out last year (2011). It was my first personal Mac and I have loved it. For everyday things it is perfectly adequate, only occasionally slowing down. I am interested in upgrading to the mid 2012 version for the USB 3 and quad core processors. I do some game playing, Killing Floor and COD4, and they seem to run well enough to play regularly. Are the Intel 4000 graphics enough to play the games similar or better to the dedicated AMD 256? I plan on upgrading to 8 gb of ram so I should be able to get up to 512 VRAM with that setup. Any help would be greatly appreciated.
