this inexpensive fix helped my frame rate

I had a 3-4 fps increase in CFS3, a 4-6 Fps in FS2002, and a 10 fps in NASCAR 2003 season. I upgraded my power supply. I was running a 250 watt PS and the Gforce4 Ti 4200 neede a 350 watt ps. I got a 400 watt single fan PS and the computer runs better. The price was about $50 US from a locally owned computer/electronics store.
