Can I upgrade my laptop graphics card?

[DamaRoja]

Hi guys! I currently have a Qosmio x875 and I'm curious to know if it's possible to upgrade my graphics card and if so what cards would be compatible? Actually I got a NVIDIA GeForce GTX670M. Ty by advance

There's an old saying if it is not broken don't try to fix it.
