so, i have the windows 7 RC bootcamped and running well. i saw it had a "rating" system and clicked it. it gave my graphics and gaming a 1.0 score! i have a new 2.8ghz mbp with the second 512 mb video card, so i assume windows was running with the one built into the motherboard and not this one. i know you can switch to run off the 512 primarily in mac, but i dont know how in windows. any ideas?
