Maybe this is just uninformed but...i7 has no onboard video so, won't you be using up (read:wasting) your video card on non-gaming and non-performance duties? I was under the impression that unless you're only going to be using i7 systems for stuff which demands performance, it'd be a better idea to get an i5 so you can switch back to onboard video for your regular applications.
*shrug* I'm just bringing this up because I don't like hearing how people spend big $$$ on top of the line stuff, only to mistakenly drive it into the ground, often during something important. Just looking out, that's all. I know you're probably not rich, buuuuut If I were you I'd get a cheaper one for schoolwork and get the one you want only for gaming. Take this for what you will.
We'll murder them all, amid laughter and merriment...except for the few we take home to experiment!
