Which is better?

[Kemillex]

Which should I choose? :
I7 4510u and GTX 850m
I7 4700hq and GT 840m

I'm not a demanding gamer, but I'd like to play games like GTA V or Witcher 3 on medium without lags. And I'm surfing the Internet a lot.
Help!

i7-4700HQ+GT840M IMHO. Might want to share the prices of both and if you have any other options outside of those two with a better GPU.

The difference between those 2 is about 25$ so the price isn't the problem here. My question is will I see a huge difference in graphics overall while gaming? Cause 850 is better than 840 but is it A LOT better?
