Hello. I want to buy a new GPU (GIGABYTE RX 460 4GB) because my actual r7-250 is not enaugh. I have a Pentium G4400 Skylake and I want to know if I need a new CPU and I want to run games in 1080p. I can accept low details. What do you think? Can I run games like Assassin's creed Syndicate, Dishonored 2 etc.?
