Okay, I have been contemplating getting a laptop for a while now. I know that I should wait until the summer for the prices to drop. Since I want to play WoW so badly and my current computer is not capable of doing that, I am forced to buy a laptop.

Here are the two laptops that I have been reviewing:

I am most concerned about their video cards. For the HP laptop, it says "Available options include ATI Radeon XPRESS 200M with up to 128MB of dedicated memory and 128MB of shared system memory". What does this mean? Also, for the HP, I am not sure if I should get AMD Sempron or AMD 64. And my last question is if I get 1x512 DDR RAM, is it easy to buy another stick online and add it to my laptop... and how much would it cost? WHICH LAPTOP IS BETTER FOR GAMES and which one is just more worth it?

THX!
