what are you gonna do with it the most , general computing , or hard core gaming ( the y40 and y50 respectively lol )
the r7 m275 is no slouch , but its not the " ultra 1080p 60fps " card either it is in the lower category of gaming gpu ..
what i mean is , gamers like lol players or dota 2 or even mmorpg gamer will be satisfied with its performance , but in games like bf4 ,etc its performance with bee adequate (medium settings 50fps+ maybe ? )
the y50 comes with a gtx 860m that will soon be upgraded to a gtx 960m if im correct , not sure when but soon according to lenovo
now this card for the price hauls ass
it is the go to mobile card if you want to play with high details at 1080p in games like bf4 without breaking the bank ( ultra-high no AA , 60+ fps in bf4) also , the y50 comes with a quad core intel opposed to the dual core in the y40
so in my honest opinion , go for the y50 and thank me later , that laptop is worth around 1000$
so your getting a amazing deal which i am super jealous right now! (xD )
select this as the answer to close this thread if your satisfied , happy computing man! 😀
