NVIDIA GeForce 8600M GS

I've got an NVIDIA GeForce 9800 GT
I'd suggest using it

You can't upgrade the graphics card on a laptop without replacing the Mobo (Too much work). You can look for a USB graphics adapter, but you are better off with the current graphics. Next time do the research before you buy.

nVidia GT 220

well i know its work to replace it,but my brother can do it.
i wouldent ask if i didnt know someone who could install it
