Hello, I'll be heading off to college this fall and am in need of a laptop. My primary use will obviously be simple things like word processing and internet browsing but I also do quite a bit of music and video downloading and movie making. I'd like the machine to run as efficiently as possible, my current desktop setup is wonderful even with over 500gb of stuff on it. I've started doing preliminary research and have looked at dell xps and sony vaio, both look nice but I'm not sure exactly what options to get (i5 480 vs 580, what rpm cpu and what size, dedicated graphics card, etc) so if you guys could help me out I'd be very, very grateful!! Thanks
