I have a hard time believing this, what games were you playing and what graphics cards are you using? And by 30hz/60hz do you mean your actual frame rate or the monitors refresh rate?

I play minecraft, wow, tf2, lfd2 at 4k@60hz on the D700 mac pro. I set everything to ultra and limit framerate to 60fps--it never drops below 50fps

Alright I can believe that, the mac pro is not a machine that an average user owns let alone can afford. You have two graphics cards that are most likely more powerful than a single card that an average pc gamer has.

Also those games aren't too graphically demanding tbh, l4d2 is the newest one and it's over 5 years old.
