I have the EARLY 2011 15 inch MBP with the 6750M card, and it has 1GB of GDDR5 RAM. I recently ran a Can I Run It analysis on my Mac, on the Windows side, for the game Skyrim, if anyone cares. And it said that my video card memory was at 708MBs, and it recommended I get a 1GB RAM card...but I HAVE one. What exactly is wrong here? Is the site wrong? Am I stupid? Also, on a side note, tried running GTA4 on my Mac, and it is AWFUL. Constantly freezes even at completely Low settings. . Yet my friend with an early 2010 iMac can run it fairly well with no hiccups what so ever. I'm in the dark here, and would love to get out of this slump so I can use my Mac for a little gaming. Thanks guys for any help or advice.
