Pentium G4600 for 1080p/4k gaming?

[AustinGreyson]

Im thinking about building a mini pc to my living room that can handle 1080p/4k gaming in dolphin. I got small lenovo case with 280W PSU but mobo needs to be changed. Im thinking about buying used mini itx motherboard like GiGaBYTE H110N ITX with Pentium G4600 3.6Ghz 2core/4threads install win10+ dolphin on ssd and keep games on 1tb 2,5" hdd. Is it already ok to play games like super mario, mario karts etc with 4k textures? If graphic will not be enough maybe some used small video card (with riser) could fit inside? Does anyone have a similar set?
