That's cause your computer is legit OP Well, for me, on high settings I get between 30-45 FPS, while on low settings I get 50-60. My FPS might drop significantly lower than that if I am playing somewhere that has a lot of mobs, heads or banners. Also, I can't set my render distance above 13 because setting it higher than that will cause horrible graphics glitches.
Alright, since i have the most beastly computer here, I know for a fact, With my 2 EVGA GTX 970's in SLI. I get around 500+ FPS on average. Around 80-100FPS with shaders.
