Omega drivers are compatible with ALL ATI cards. Check out their
websites. And no, ATI's own drivers do not deliver best overall
performance - that's why there are tweaked drivers out there like
Omega and at least 3 other types.

And difference between all those modded drivers in
practice is something like 1fps and max 100 points in
3DMark compared to official Catalysts, so we are
certainly talking about massive differences here :-)

Not to mention that old familiar "Whoa, this game truly
FEELS like running smoother with these drivers!" thing.

Isn't it always like that when people update their drivers,
everything mystically feels like running much better.
Advertisements from the driver's author also do help a
bit creating this illusion...
