If you can wait a few months, Sandy Bridge and Bobcat will make ideal smallish laptops.
For now, any 2.0+GHz dual core laptop with Intel HD or 4250 graphics can run those two games smoothly at low settings. Avoid Intel 4500 graphics and also Atom cpus (performance problems), and AMD cpus that use DDR2 (poor battery life). My 2cents.
World of Warcraft
thanks for the responses guys!
yeah integrated is definitely not a path i will go down.
I'm really interested in what you all think about this laptop:
The 10 hour battery life is impressive. The 1.2 GHz cpu would of worried me, but Asus seems to have solved that with it's Turbo33. The 310m graphics is a bit light, but it will run 1366x768 games on low settings. Good speakers, hdmi, dvd.
There are other systems that give more performance, but with less battery life. Balancing performance vs battery is a judgement call you have to make based on how you plan to use it. Overall, it looks like a great light gaming laptop for a student to me.
