My laptop that i use mainly for school isn't too good for gaming (duh) and I am looking for a cheap prebuilt upgrade to build up on. These 2 computers I have to share are at least 2x better than my current one. I want the best computer to use for upgrading, and I will be putting the specs of my current laptop to show the upgrade worth, and such. I want the computer nerds (:P) to help and pick the best computer that will be better for running games like CSGO, TF2, and MC, with minimum lag whatsoever with 2 monitors or more.

Current Laptop:
2gb of RAM
Intel(R) Celeron(R) CPU N2830@ 2.16GHz (That's what taskmanager says)
Prebuilt, not sure what motherboard, I'll include a screenie
