Ok so I decided to upgrade from my Geforce 8600GT to a 9800GT so I could get FS9 and FSX to run a little better. Comparing the two cards it should be night and day right? Both my flight sims run WORSE now with the better card. I know MSFS is cpu intensive but that is crazy. Anyone else ever have this? My system isn't a speed demon but not a slowpoke either (2.66 Mhz duo-core 2g ram) My driving sims show an improvement but flight sim sucks. Any help would be much appreciated!

Cheers
