That's perfectly fine, prime95 is a synthetic benchmark, it isn't a realistic portrayal of what to expect in general use.
I'd expect temps in the mid 60s or low 70s under high gaming load, not to worry.
They're great temps, unless it gets above 80c constantly in normal gaming use, no need to worry.
Are spikes up to 50c when doing things like opening up multiple web pages normal? It instantly shoots back down to idle temps though. I never seen temps act like this before.
I'm new to Intel CPU's. My FX-8350 never went over 62c. Even with the stock cooler.
