ok… but one question, why should turning the refresh rate down on the monitor make the screen less jumpy, when the video card is actually able to produce refresh rates of like 120 Hz? I’m thinking the monitor just couldn’t handle the refresh rates the card was producing, so it makes more sense to me to adjust the refresh rates on the card (if that’s possible).
anyway, I’m going to try and combine Gozu’s and gotpasswords’s advice, since they seem similar:
so… after uninstalling my video drivers (in Safe mode? or no?), I should reboot, Windows will be ugly, and then reboot again (to be safe), with the monitor still plugged into the video card the whole time? then shut down, swap video cards, install new drivers (I have a cd with them on it), and THEN try to adjust the monitor refresh rate?

To answer your first question, depending on the kind of jumpiness you’re experiencing, it could simply be your monitor not being able to handle the refresh rate being fed to it. (This could also be a sign of your monitor preparing to give up the ghost.) By doing this through Windows, you are essentially adjusting the rate on the card, by telling the card not to try and refresh as often.
Driver uninstallation…I’d probably not bother with safe mode, personally, but that’s because I hate safe mode. It probably would be, as the name implies, the safer way to go, however. And, yep, with the monitor attached to the video card. (Attach the monitor to the new video card as well, once you get it in there.)
The rest you have correct (yes, adjusting the refresh rate would be the last thing to do).
You may not even need to adjust the refresh rate if the card switch goes smoothly and fixes your problem. That said, there is always a chance that the problem is driver-based, and getting the most up-to-date drivers off the ATI website will do better than the drivers off the CD. I suppose you could always do the drivers off the CD first then upgrade later if problems persist.
