Hi,
Normally with your laptop it's the gaming dock that produce all the performance graphics you need. What you can do is to check the inside of your laptop and see if the GPU is not soldered because if it is that means you can't upgrade the GPU.
Hi! Thanks for the answer... i thought that so... he's selling it for 600 bucks...but without the gaming dock ,or at least possibility to upgrade the gpu...it doesn't worth for gaming...i mean strong cpu i7 4870hq, good ram 16 gb, good storage 256 gb ssd...but integrated graphics...
