Here we have the new 4.6 Catalyst drivers in a nutshell. One thing we can honestly say is that if you're trying to break the Aquamark 3 record, stick with the 4.5 drivers as it seems to take a big hit with the latest release from ATI. We see a little jump in most games but at the end of the day its nothing that you would really be able to notice in games - the difference in some games is only an FPS or two.

If you're benchmarking 3DMark 2003 quite heavily and trying to break some records (like me recently as a bunch of new high-speed products hit our labs) we would definitely recommend installing these new drivers as we saw quite a good jump in both resolutions and when we had AA and AF maxed out.

It's great to see Overdrive is available in the new drivers. Though, in all honesty, a lot of people buying the X800 cards will know how to overclock manually and will not be afraid to do it. Nonetheless, Overdrive is a nice little marketing feature and as you can see you do get a slight jump in performance. There can be no harm in using it if you don't want to manually overclock for whatever your reason.
