yes it does...modern games work fine on Core i3 but games like Assasin creed 4 and unity are very demanding games and watch dogs as well.upgrade your Ram to 6 or 8 Gb atleast.or consider buying whole new system.Gtx 750 is a decent mid range card but current games need much more powerful GPU.Gtx 750 have many other uses its not very good for gaming in my opinion.
