Hi, i upgraded my system to a i7 870 CPU with 8GB ram, Asus 250 GTS 1GB graphic card and a MSD P55-GD65 MOBO. Cooler master 850W power spupply.

I'm running FSX with REX, and UTX and some Brussels Scenery from Aerosoft. I only get 10 to 15 FPS at low altitude. Is this normal ? I used to run a q6600 CPU and ran 25 FPS without any problem.

Any suggestions ?

Regards,

Marc;
