Thanks to the forum members who recently helped me select a video card and power supply. Based on their input I purchased an EVGA GF6800GS and new PS for my PC to replace my GF FX5200. I plugged everything yesterday and got it working this morning.
The Power Supply, a 430W ThermalTake is of much higher aparent quality than my old unit and the video card... well...
Previously I could run FS9 mostly high settings at 800x600 16bit, with clouds turned WAY down. This morning it ran smooth as silk with everything, including clouds, max'd out. Only Anti-Aliasing slowed down the frame rate perceptably, and all of this at 1600x1200 32bit. A monumental improvement.
I only had 15 minutes to play with everything before work. I'm still using the drivers supplied from EVGA and need to update. I tried the nVidia drivers downloaded from the web (Forceware) but they didn't recognize my card as a supported product. I don't have a clue why...
