OMEGA drivers

While most people choose to use the official ATI Catalyst drivers, the Omega drivers were developed for users who are a bit more adventurous and are looking to squeeze the best performance out of their graphics cards. The Omega drivers were developed by Angel "Omegadriver" Trinidad as a hobby. You can visit his website and the official home of the Omega drivers here.
What makes the Omega drivers so special? Well, aside from the fact that they tweak the registry and various other settings to optimize performance, Angel "Omegadrive" Trinidad is also a member of ATI's Catalyst beta driver testing team. This means he is able to incorporate future Catalyst optimizations into his own drivers! This effectively gives Omega driver users access to future Catalyst benefits, even before the official release!
