A turn will use as much processor as you can give it, that is really the only deciding factor as to how fast it will resolve. Keep in mind with multiple cores it will still only use 1 core. I usually overclock my system to 4.16 to run really large games 1500ish provinces, 70ish nations and I never get anywhere near an hour turn time. At the most I get 1.5 minutes, so something definitely seems fishy.
