Laptop graphics card

[mike ming]

I already have a discrete ATI mobility readeon HD 3450 but not good for high end gaming. so thinking of changing it.Where can i buy graphics cards for laptops in India ( preferably Bangalore.)
also the price? also is it feasible to replace repalce it by Nvidia cards?

dude!!
Here is what am talking abt. most of the laptops dont support this . Realized mine also does not. but there are laptops with this feature.Discrete graphic cards can be upgraded. just like add-on card . they are available in both type integrated type(saves hell lot of cost to the companies) and integrated cards( end user is benefited.)

My question is are these cards available any where in india or hav to buy from outside the country only?
