FYI, the new X3 release has a dramatically improved verify as far as time is concerned. It looks the same as it always did but it was nearly 50% faster on my test.
Anyway, I do not know about the FX1700 but I run the FX1400 every day and I have no complaint with X2 or X3 using that card.
Have you tried getting the latest drivers directly from Nvidia's website for your 7650 ? Could make a very big difference...
If you try it, download the new driver, uninstall your current display driver, then on reboot when it "finds" the video card and wants to install the driver CANCEL, CANCEL, disable your antivirus, and then finally install the driver you downloaded.
