I asked this question on the Mac Gaming section, but realized I'd probably get an answer on the actual MBP forum itself. 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? 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.
