Is it possible to upgrade my laptop's video card, and what is the best replacement, and where can i buy it?

HP-HDX18 Notebook PC

Intel Core2 Duo CPU T9900 @ 3.06GHz

8.0 GB RAM

64-bit windows vista



current video card: NVIDIA GeForce GT 130M (PCI bus 1)|||unfortunately laptops have integrated graphics cards so it is impossible to replace, you would need to buy another main board with a better GPU and that would have to fit the dimensions on the laptop, best to just buy another laptop w/ a better GPU|||Graphics cards are usually specifically built for one model of computer. It would be difficult to find a correct match.|||It is not possible to upgrade a laptop graphics card because it is interrogated into the motherboard|||Not possible on any laptop!
