Hello to everyone, I have the following problem.

I want to buy a new Graphic Card for ACER 5520 laptop

The laptop is coming with ATI Radeon X1250, but I cannot find and buy one.

I am thinking to buy NVIDIA GeForce 8400M, because I saw somewhere that is combatible.

Can anyone give me any advise? Is NVIDIA GeForce 8400M going to work on my laptop?

Thanks in advance

You need to purchase it from market froms requirement. You need to search better near you.
