Hi welcome to DH
I suggest you start with the official driver & control panel, to make yourself familiar with the new driver.
later on you can always try the Omega's, when you do install the omega's be sure to deinstall the controlpanel, and after that you can install the omega's.
If you had a other brand card, I advise to use DH Drivercleaner *be sure to read the read me!!*,
