Apprently increasing mac's ram can increase graphics speed very slightly but this mac mini was originally bought as a server so it has 16GB ram. I dont really know a lot about graphics cards other than my mac uses Intel HD Graphics 4000 1024mb which isnt ideal for gaming as it uses CPU as well i think :S.
I love OS X and dont really want to buy a new gaming PC for the few games that i play, however I am willing to spend some money on some sort of external alternative preferable not too expensive. I play one or two games on Mac OS X but also dual boot windows 7, for the rest. Or some sort of dock for a graphics card.
However I've seen one or two wesbites mention external thunderbolt graphics cards.
I know that the graphics card on my mac mini isnt upgradable as it's built in.
