Average 60 FPS should be achievable or at least with the vast majority. Minimum of 60fps there are already games that will drop under 60fps and AAA games will continue to get more demanding.
Most game settings don’t impact the cpu woakload. In most games changing from high to ultra will likely only impact gpu workload so if your cpu is limiting you at ultra settings it will also limit you at high settings.
This is all very game dependent. If you are not playing modern cpu heavy AAA games then 60fps minimum won’t be an issue.
