the newer models of xbox are a lot better now just make sure if you get a premium it has hdmi because thats the easiest way of knowing its a newer model and runs cooler, i'd say get one and gta4 is awesome i recommend it to anyone, your pc is capable of anything at the moment even if you cant play with the highest settings its about enjoying the game not having it look amazing, as long as your framerates are ok theres nothing to worry about
