8600GT
Most laptops do not have separate video graphics cards. Those that do are limited to certain ones. We will need your laptop brand and model in order to help you with this one. There are space limitations, connection requirements, and cooling patterns to consider.

Oh!
@raybay

I was considering The Dell studio 17 and XPS 1530...the studio 17 has the HD3650
mobility radeon while the XPS 1530 has the 8600GT mobile...i am going for a laptop that will be my ageing desktop's replacement...so i prefer a 17 inch screen.....and i want to avoid those expensive Toshiba and Sony laptops...i also dont need a card that belongs to the 8800(high end series)..

Also how does the mobility radeon HD3650 perform?
