If you can aford it I would go with both at roadrun said. You definitly will want a laptop for college. 2 years ago I took a class and a laptop was required just to let you know. Also if you type reasonably fast there may be some classes where typing is much more efficient than trying to write things down. Some semesters I find I take my laptop everyday sometimes I hardly ever take it depends on my classes. I'm debating on buying the gateway the only thing I don't like about it is size. My current laptop is 14inch and only 5lbs.
I will say 600-800 on a laptop and 800-1000 on a pc is not a bad idea unless you really want mobile gaming.
I appreciate all the response. I'll see what I can do about getting both a laptop and a desktop. If not then I'll probably get the laptop. The only reason I was choosing the laptop mentioned was if I was going to get a laptop and not a desktop, I want one that will play games and the one I mentioned does pretty well at a good cost.
