Upgrading PC for 1440p (2k?)

[luisxd]

So a friend asked me to upgrade his PC cause he's going to get a 4k TV and wants to game on it. His budget isn't too big so i recommended him to stick with 1440p for now.

Currently his PC has an i5 3470, RX 470 and a Seasonic 620w, and i was thinking adding a gtx1070 - 2060 and maybe get an i7 3770

what do you think?
