About being able to run FSX-

Officially the back of the box says it requires 2.0 GHz or higher. I think your computer will be able to run it. I used FSX for a long time with a Pentium @2.1 with 4GB of DDR3 RAM and an integrated graphics card, a terrible system, in other words. However, it worked for me. Now maybe I was being very tolerant with the frame-rates and crashes I got. However, FSX's box does say 2.0 GHz and up. Do not expect high resolution textures, though. You'll have to prioritize your aircraft textures over scenery and such, or else your forests might have trees in them, but your instrument panel will be a bunch of pixels. You'll get a functional simulator, but not a beautiful game. If you're content with that for 25 bucks. keep in mind, some add-ons and mods require better specs.

I hope this helps,
