Can I upgrade my laptops Graphics card?

[ingridcambra]

Hi I have ASUS laptop 15G29N005501 (Model: K55V) and I wonder if I could upgrade its graphics card from NVIDIA GeForce 630M 2Gb to GeForce 660 2Gb or to GeForce GTX 760.
I have an i7 3610 QM 2.3.GHz, RAM 8 Gb, 80 Gb free HDD

P.S. Or maybe I can add an external graphics card, is it possible?

No you would able to do either. Your video card is soldered onto board so replacing it wont be possible.
