Have you tried un-installing the new drivers and go back to install the older drivers that came on the CD? Just to make sure that it's actually the new drivers that are causing the problem.

If it's a beta driver it could be the issue; sometimes they help sometimes they hinder. Personally I never use beta drivers, I always wait for the official stable releases. As was suggested, you should test it with the previously installed driver just to be sure.

You don't need to go scouring the net or searching for the disc that came with the GPU in order to find your previous driver. Just do a system restore to the day before you installed the new driver - if the performance has gone back up, you know not to update the driver to that particular version again.
