I have a Sony Vaio, I think VGN NW240, I think 350 gb. Ive had it almost a year in january, it gets light use because I have another laptop to do work on, I only really use it for watching movies, but dont really have much on the hard drive. I really want Civ V, is my vaio strong enough, I dont want it to slow down or anything like that, im too happy with it for that to happen!
