How many FPS do you get.....

Hi guys,just did a fresh install of windows 7 and fsx along with all the addons. Followed the process: http://www.simforums.com/forums/topic34141_post198187.html#198187 Was wondering what you all get with the pmdg 747 and orbx scenery(ybbn if possible) and rex. Im doing slight changes to cfg etc and relaunching fsx to the test flight which has the 747 parked at a gate at the orbx ybbn during the day with a few clouds..... Getting around 15-20fps. Id hate to think what it would be with rain etc....
