Can my laptop run MW2?

I want to buy Call of Duty 4: Modern Warfare 2, but I'm not sure if my new laptop can take it. Here are the specs (similar to my old one, which is broken):

2GB DDR2 RAM
2.1 GHz AMD Athlon x2 QL-65
Hard Drive 320GB 5400RPM
512MB ATI Mobility Radeon HD 3400
IDT High Definition Audio
Standard 14.1 inches display at 1280x800 resolution

Will it run good on medium settings?

Thanks!

yes it can

On what type of settings would it run smoothly?
