Just installed a 9600Pro and kept having problems with the Catalyst 4.2 drivers. Read that the 3.7 drivers helped solve some of the problems I had been having so I downgraded and system is bug-free. My question is, that in regards to performance, am I missing out on much sticking with 3.7 instead of the newer releases? How much better is the 4.2 driver, compared to the older 3.7?
