Is a laptop with 2GB memory, Intel Core 2 Duo Processor 1.5 GHz okay to play internet video games?

I wanted to buy a laptop that I could use to play World of Warcraft. The laptop is from Gateway. Graphics is Intel GMA X3100. Chipset is Mobile Intel 965GM Express. Hard drive is 160GB at 5,400rpm. A friend of mine said it would be okay, but just wanted to ask for other opinions. Thanks!
