I would like to find or create a good Mac for gaming guide that relates games by their specs to the gpu req to the macs they are in. So I can get a big picture of what macs can play what games and what gpu is under the hood in each case. I will start with my Mac that will not play much of anything if at all. I'm looking to upgrade this year for a decent gaming Mac now that steam is here. Mid 2007 Mac mini Graphics- shared with main memory Intel GMA 950 using 64 MB of DDR2 SDRAM Please add your info and what you know or any games you know that will run on my model since my submission is incomplete without them.
