| There is actually a method for installing them that you have to go through, else you get issues like that.
You need to uninstall the old drivers, reboot into safe mode, run drivercleaner, install new drivers and reboot. What happens if you don't is the previous drivers conflict with the newer version, and cause issues like you have experienced. I should have told you about that.
Overclocked, you will get more performance from the newer ones, if you do the proper installation. With the improved overclocking on the 91.33s, you should definitely get better scores.
