Same. System Requirements Lab doesn't factor in anything that might augment the MB being taken from the card. My card is only 64 mb, and fails that part on the site, but can play most games (I can play Spore on it at medium GFX) So use it more as a benchmark or reference, and not the cold hard truth.
I also have an unofficial driver for my card, since I use an integrated laptop chipset, and it still works like a charm.
