Planning to get a new CPU.
Which CPU will have more perfomance when using 3D geometric, because I am not able to play at 1080/90fps on RE2/RE3 neither RE7 2K/90fps using R5 3600
Get the 5800X. The Ryzen 5 series has a considerably better single core performance than the older series 3 models. The 5800X has enough cores for all gaming purposes, so what counts is the single core performance since in almost all games the performance in the end depends on one main render thread once you have four (or maybe six for newer games) cores available. Adding more cores beyond that usually doesn’t do anything for games.
