@ garsands - what rez are you running FSX at?.....
I was running FSX at 2560x1440.
My monitor is a Dell U2711 it does not down scale well at 1920x1080 it looks all dull.
To power this rez my system is-
CPU i7920 @4.1 GHz
6GB Ram
2 x EVGA classified GTX580 3MB < not O/C no need to at the moment.
Harddrives are SSD
This system plays all my games maxed out at that rez with added settings using nvidiaInspector without any problems. I think a bench mark game at the moment is Metro2033 I have finshed it maxed out without any slow down in FPS.
FSX is the only game that it does not run well with.
The weak part for FSX is my CPU but the next best on air would be 5GHz but I would need something more like 7GHz CPU before I would even think about upgrading just for FSX.
For the £500+ it would cost I could buy lots of new DLC for Flight & still play all the other new games maxed out.
I like to play my games at max settings all the time. So if a game offers me the option to have 30 AI planes in the air then I want 30 planes in the air.
As I used REX 2, Orbx I have to have all setting on high to get the full detail out of it.
If I need to buy better gear then I will, I will get the best that money can buy but at the moment there is not a 7GHz min CPU for me to buy.
The last staw for me with FSX was at xmas I bought Orbx Melbourne loaded it up with AI Traffic & all the works & every time it would crash my PC, if I dropped the detail settings if would be fine, but I know I am missing lots of extra detail that's there but I can't run it & I have paid for it.
I had already run this program before hand

I had also used these settings

I fully understand that the nvidiaInspector settings was the big killer of FPS but I was using the RealAir Turbine duke payware plane, without the extra settings the HD cockpt would have shimmering around the dials all the time.
I really liked FSX I have nothing against it as a program it's just the low stop & go FPS that I can't live with. I have a good powerful system that runs other new games maxed out fine.
