I am currently using a nexus tablet; at first it was cool, but now its just a slower and less capable laptop. I am looking for a casual use laptop with some gaming capabilities. I will probably spend most of my time playing tf2, so no super intense graphics. As for other specs, I don't want a screen much larger than 17 inches or smaller than 12. I would prefer a PC running on windows 8 or 7, but do not want a touch screen. A separate number pad would be favored but not needed. Hopefully you can help me find this all for under $500!
