greetings,
i m thinkibg of buying a good laptop with nice performance and gaming experience and strong enough to handle hours of gaming
so lenovo y5070: (don't mind frensh words)

Ecran 15.6" Full HD LED, Processeur Intel Core i7-4720HQ (2.50 GHz, 6 MB L3 Cache, up to 3.50 GHz), Systéme d'exploitation Windows 8.1, Mémoire RAM 16 Go DDR3, Disque Dur 1 To HDD + 8 Go SSHD (5 400 tr/min), Carte Graphique Nvidia® Geforce® GTX 860M ( 4GB )
basically same as y50 but difference in gpu vram an ram i guess wich i don't need for the time being and same price what worries me is that vram i'm not comfortable with this difference is gtx 860m 4gb better or not cuz seems gtx 860m 2gb is popular and have good reputaion more than it?
what should i choose?
