Then you are using a terribly inefficient and old CPU mining program. I get 3.9MH/s per core of my non-overclocked 1090t.

True, my CPU is not a top-notch one anymore, but hey - even your CPU is just at 3.9 mhash/s. Compared to 370 mhash/s, this is a ridiculously low value when you compare CPU vs. GPU in general. If your gfx card is a slow one, and your CPU is doing better - stick to it. For me my GPU is more than 100x faster than my CPU.
