Hey all. I just bought a sony vaio PCG-K25. It comes with that video card ATI Radeon IGP 345 M. Apparantely this is an awful card to use for any 3d applications, and it also uses system ram as it's ram. I don't have much experience with laptops, could anyone please tell me if this card in a laptop is replaceable with something else ? ? Any advice would be greatly appreciated!
