Nice upgrade. I recently bough a gtx 770 and just let geforce experience update the drivers, and wasn't getting the performance I was expecting. I then used a program to completely uninstall all video drivers and reinstalled the new drivers, and got the performance I desired. So yeah I highly recommend uninstalling the old drivers and installing the new ones. Keep in mind after uninstalling the old drivers, if not done in safe mode, the screen will go blank. Just hit the power button and restart the computer and you will have a low resolution display again, then when the new driver is installed, restart and you will be good to go with high resolutions and gaming.
