[Intergrated graphics possible?]

Most likely a 2015 model so i guess that would be last gen (4th?) i don't really keep up with computer hard ware. Is there a huge difference between gens in say an I5 chip? My current laptop is a 2nd gen I5 i mostly assumed my 2g ram is whats killing its performance for anything game related.  I do need a new laptop. I am just wondering if it would be better to get a slower processor and a crappy dedicated graphics card or just for for an I7?

[Intergrated graphics possible?]

Looking to buy a new laptop. Any one running this game on an I7 laptop with integrated graphic? Would I be better off trying to find an I5 laptop with a 2g ram graphics card? I would find something with 8 gigs of ram either way just trying to figure out if more processing power or a crappy dedicated card would be better for this game.

 

Thanks in advance.
