i am looking for PC gaming only. Like if GTA V launched then i am unable to play. i want to play games which required higher graphics card like nfs, crysis, fifa, sim, mass effect 3 etc etc
to use external GPU you'll need thunderbolt or something better. any other port will easily get bottlenecked. in short not possible, not feasible. should have checked well before getting the laptop.
Actually it was a very old failed technology. Using so called 'external graphics card' won't have any effect on performence.
And the answer to main question is No. You can't upgrade or change the graphics card of your laptop.
