Hello, so right now I have a Multcom Kunshan P177SM (Clevo P177SM) with following specs :i7-4700MQ2x4GBGTX 780M256GB SSD + 1TB HDDAnd it's not a terrible laptop at least for me, but I would like to have a bit more, stable FPS in games like The Crew 2, Rise of The Tomb Raider, DiRT Rally 2.0 and one of the main bottlenecks if I'm not wrong is the GPU.So, I'm kind off thinking about upgrading it to GTX 970M or if finances allow, GTX 980M. But I was wondering, if there's something I should know before doing it or is it as easy as just getting the old GPU out, installing a new one, reinstalling drivers and i'll be good to go? As I really can't find any proper info online.
