Re: about my new graphic card x1650pro
I think your CPU is bottle-necking that card. The X1650Pro is a good card, I used the PCI-E x16 version for over a year, and had no problems like that with it at all.
What are your full specs? Also include your PSU wattage if you know it just to be safe, just another one of my random hunches.
You could also try completely uninstalling and re-installing all of the drivers just to make sure it's not that problem.
