Although your processor is fast, you're going to need way more video resource to get the frame rates up. I'm running a Pentium 4 2Ghz with a Radeon Pro video card with 256 Mb VRAM and a gig of memory and still only have 5 to 9 FPS with all the sliders to minumum. Intel and AMD are introducing Quad core processors next year, along with screaming mother board speeds and "dual" video cards. Throw a pile of memory on that and that might get the rates up to FS9. I'm sure that's what MS built the FSX on. As far as display settings, there isn't much you can do other than to move the sliders for scenery, weather, aircraft and yes, sound, down to the minumum that is still flyable. I've had everything to minumum and still didn't even get 10 FPS.
