If your laptop is a top of the range one, ie you paid £1000 or more for it, there is a slight possability that it might have unpgradeable graphics. I have only ever seen about 3 perhaps 4 laptops with this option and they are very pricey. The only one I can think of ofhand was one of the Alienware ones costing just over £1500. If you tell us what laptop it is I'm someone will double check. But they are very expensive and very rare. I would think Jackcoms would be correct in what he says.
