Well, there are the new ATI Catalyst 4.7 drivers for your viewing pleasure. The performance jump isn't as great as last time and there is nothing new like the last release which brought us Overdrive for the new line of Radeon X800 graphics cards - on the outside, the ATI Control Panel looks exactly the same as the 4.6 version. While there isn't a big jump in performance (and in fact, a decrease in certain areas), it is always a very good idea to update to the latest set of drivers as it fixes up some of the bugs in your favorite games that were in previous releases and this is usually a good enough reason to update for many.
We did see a small jump in 3DMark 2003 which we saw in the last release of drivers so it will be interesting to see if this continues across more driver releases. Aquamark 3 also saw a little increase.
While some of the synthetic benchmarks aren't up, as you can see for yourself, the real world gaming benchmarks don't show an increase in performance. If you're not in the mood to go through the process of reinstalling the latest drivers, you're not really going to be missing out on too much but if you are still running something older then the 4.6 drivers (on a more recent ATI based graphics card) we would recommend that you take the jump now as you should see quite a good jump in performance when compared to some of the older releases from past times.
Until the 4.8 drivers are released probably sometime next month, happy benchmarking!
