i can't believe your listening to this BULL.. even on the box for HALO2 it says Nvidia 6000 series cards and up , so the 7000 series will be fine. processor says 2gig. but a 1.9 should do it , it requires windows vista , unless your a pirater and they have XP cracks.. but direct X10 was not even around when this game was made. this game was made for XBOX and is not a PC hog.. the grafix are a tad better than HALO 1 , but still directX9.0c ,, i suggest you put the entire error message in the google.com search bar and you'll find your answer on the microsoft support forums. always get a second opinion from a true gamer , not a weekend warrior.
