I'm looking for a laptop. I prefer something with a graphics card with dedicated memory but most of what I've seen are using shared memory.

I'm wondering... in terms of performace (although I know dedicated memory is better... ), how do I compare a card with 64MB dedicated memory to the one with 128MB shared memory? Is the one with dedicated memory still better even though it has less memory?

I need a graphics card that I can play games like Sim City 4 and some maps utilities...
