We don't have anything huge on our hands but it is interesting to see that the WHQL driver that was provided by Sapphire does give us a slight jump in performance. What this mainly tells us though is that there is going to be some performance there for future driver releases which will keep us on our toes.
We found that with the non-WHQL driver installed, Doom 3 was unable to benchmark when AA and AF was enabled but had absolutely no problems running at these settings on the X1800XT.
We are really looking forward to the release of the Catalyst 5.11 drivers and it's safe to say that nobody should be writing ATI out of the graphic card books just yet as we don't doubt they aren't going to put a fight up. While nVidia's latest driver sees a very good performance jump on our Dual Core system, it still isn't an official driver and their current official driver is dated more then six weeks ago with still a few weeks to the release 80 series comes out.
If you have purchased an X1800XL already and want to make sure you have the latest driver you can simply enter Catalyst Control Center, go to View and click advanced view and make your way to the information center. The particular part you are looking for is the Driver Packaging Version and the particular one we are after is 220.127.116.11-050921a-027133C otherwise wait till ATI officially release the next set of Catalyst drivers in two or three weeks time.
