i installed Halo 1 on 7 and experienced MAJOR frames-per-second problems. i had to turn down the graphics to their lowest settings to get it to work. i was wondering if this was because of the interface using up all the graphics memory or something else. i plan on upgrading to 7 when it's finally out and i want to know if i need to upgrade my graphics (again) to be able to run my games (which is really just halo 1 (possibly 2), UT04 and UT3).
