FS9 on my new system

Well, now that I have a new system ready, I need to get FS running well on it. My system specs are below, followed by my current display settings. I tend to get extremely bad framerates (5-10) in either heavy weather or high-density areas. I know I need to lower some things, the question is really what. Sorry if I misplaced this, but it seems the most likely place to go. Good god, I feel like a newbie . . .
