the pc gamer :
nvidia because it has more vram
But weaker performance compared with HD 7550M. 2GB for entry-level GPU
is advertising.
Have u look into AMD APU? A10-4600M + HD 7670M (A8-4500M + HD 7670M) would do better than single HD 7550M.
Is these laptop which pair with GT 610M/ HD 7550M has i3/i5 CPU?
