I'm running an amd fx8350 @4.96ghz with a gtx770 @1384mhz/3505mhz and with Nick n bible tweaks I get 44fps max 21fps min and 33fps avg. fsx mark11. that's on the second run after fsx is opened so the textures are already stored in the memory.
Next week I'm upgrading to a 4790k and oc the nads out of it like the fx because it will also be custom watercooled like the gtx770 and he will have a twin next him next week as well then I'm going to re run the tests again.
