Is the new set of Dll good for a 9800 GTX ?

Image shearing comes from disabled Vertical Synchronization. You can set that in the driver setting to "force on".

Just another idea:
Did you buy and install your new computer from scratch or did you just exchange the graphics card? If you just exchanged the card and didn't reinstall the system, you should uninstall the previous drivers, even if they were nVidia, too, and run DriverCleanerPro to remove all remaining settings in the Registry, reboot and install new graphics drivers.
