VRAM Reporting Bug - 2GB Cards
In 10.5.8 and 10.6 all cards with 2GB of RAM are mis-reporting their VRAM to OS X. Most applications don't care about this, but games may not run as the card doesn't meet their system requirements.

It has been noted with some success that a PC edition card can have a new (larger) ROM chip soldered onto the board and then flashed with the ROM from the EVGA GTX 285 to basically become an official card. Try at your own risk!
