Gaming Laptop (Dell?)

[nicksource]

I've looked around at Laptops, a lot out there! The Dell and Acers look good, I'm just wondering what's the best GPU, the ATI 3450 or the Nvidia 8600GT?

At the moment I like the look of the Dell Studio 15 but would the Dell M1530 be better? The only differences is the card as mentioned above from what I can see.

Budget of around £600, wish to play Source games and CoD4.

Thanks in advance.

Found its the 8600GT so going with the Dell.

Is it worth upgrading anything on them when checking out?

Do you have a source that says they are doing this?
