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?
