Will this run FSX DESCENTLY?

I don't mean to put a dampener on things, but no chance.
FS9 will run Ok-ish on that, your graphics card and memory are letting you down. Load FSX and your processor will struggle too.
Sorry.

That computer for FSX is a no no. That will have trouble running even FS9. I would just not even buy FSX if you can only afford that computer.... you just won't be able to enjoy it: no trees, no waves, no scenery and probably blurry textures. I'm sorry about all this but it's the truth... FSX is really really demanding!

It's a good thing i didnt buy it then. I thought about buying but I decided to save up my money for something better.
