safe to have 2 GPU drivers installed?

[thunderdome]

I have 2 GPU's I am trying out to see what works best for me, a 560 ti and an 6970. Is it safe to leave both drivers installed so when I swap I don't have to reinstall drivers? Or should I just uninstall overtime I swap?

This is in windows 7 home premium.

thanks

Remove a card, remove the driver.
