Replying to Looking for a new computer

Going off to college next year... Will be in the market for a new laptop in the forseeable future as this old guy is likely to hit the shitter at any time, so any recomendations for computers would be greatly appreciated.

I really do not know much about computers, but i'd like it to be able to edit well (gopro, maybe dslr/ other digital HD video). I'm really not that interested in Macs since they are considerably more expensive and i've used PC for most of my life. I imagine that I will also be purchasing an external hard drive for it as well. Ummm i think that's all, unless there's other things you would like me to specify.

And of course +K for good answers.

Thanks NS!
