The best advice I can give you is to turn off the FPS counter. If the game feels like it's stuttering, turn down the quality. If it feels fine during gameplay, don't fuck with it, and under no circumstances should you enable an FPS counter or frame timing graph.
If you're anything like me and you do enable the FPS counter or frame timing graphs, you'll spend more time optimizing performance than actually enjoying the game...
Great pick. The X670 and E variants are insanely overpriced for what they provide. People don't need PCIE 5 when there aren't even any non-SSD components that use it.
