Not sure the fps increase from HDD to SSD. Load times... oh yeah. FPS? Not really.
@Im Weeb, think of it like bought a larger car with a bigger trunk. Not a faster car, just one that can carry more each trip. Since you're not loading the first car (6700) with enough stuff to make more than 1 trip, it's still more than enough.
Not sure who sold you on the 3800X, but I'd say you were not fully informed what you were getting.
