I have a notebook. Dont know the name model. But i can run most games today on low graphics and alot on higher graphics. Here are my specs:
CPU: Intel Core i3 2.6 Ghz
GPU : Nvidia GeForce 325M 1GB
With these specs i play Mw3 (high graphics) on 150 FPS. I play WoW on 120 FPS (also high graphics)
So you just need to pick a computer similiar to mine if you want to have a descent gaming laptop.
dude fuck the brands, the important is whats under the hood. i've been playing with an acer for 4 years+ with no probs. anything with an i5 or i7 and with a 1gb dedicated graphics card should do the trick.
