Is it bad....

[B767-300]

...for your memory, if you have a lot of aircraft add-ons?
I have probably 80 aircraft total on FS9, and am wondering if this takes up a lot of memory, and impedes the progress of the game to have so many.

Well, it depends on your rig. If you have a new-ish computer, it shouldn't pose as a problem... I'm running around 150 or so planes with an older system and I'm getting okay frames... If you're getting bad graphics you can lower how high you want your frames, or just lower the graphics...
