ADDITIONAL COMMENTS: I can get the student discount on windows 7 for 60$ (think they upped it from 30   ). I want to get some decent fps as well, maybe 30 - 50 while raiding medium graphics (max if possible) (also have Phoenix mount, I've heard that it messes up your graphics card but i haven't found any proof). I would like it to last for at least 2 years if possible aswell.
