The i7 4770 will only be marginally better. I don't think you will have any issues at all as long as you keep your settings reasonable to that build. As it's already been stated, you might have some hiccups in a heavy raid setting. But there aren't many builds of that caliber that wouldn't stutter under that kind of demand. I have a close friend that did a budget build with a G4560, 8gb (dual 4gb 2400MHz), and 1050 ti. He has no issues at all unless in those high demanding situations where he stutters a bit but that still doesn't render it unplayable by any means.
