yeah i do agree with the ram there, gaming will be the main thing im doing on the laptop
in terms of games that im gonna play, probably tomb raider, battlefield 4 and hardline beta, maybe i might get titanfall, Grid Autosport, Farcry 3, but what i am thinking is that im not going to be playing them at maximum settings all the time, tone down Anti Aliasing and anistropic Filtering
Also in terms of a price difference in the UK i worked it out to be a extra 18-20% extra cost for the 870 over the 860, although thats £200 its not that bad.
