I want to purchase a Mac Mini 2011 with IHD 3000, and plan on gaming just a bit. Cod 4, minecraft, battlefield 3( Low-med) settings. I was wondering if i should just get the intel hd 4000 graphics with the 2012, if it really is faster? has anyone compared the two? big difference? my friend is selling me his Mac Mini Mid 2011 for $390 not sure if i should go for it. thoughts?
