Has any one tried this game on the iMac 6770M video card? I am thinking about getting a new iMac but I need good to high quality on this game. Found examples of play on HP laptops with this card. Just none with iMacs yet. I had posted this on macnn but just not enough users there to get a answer quickly and incompetent mods have finally pushed me over here. Im hoping some one with a iMac with the 6770M has tried the final retail game out and could elaborate what settings levels work. I'm aiming for high, I can live with out Ultra.
