The site Hardwareoverclock has posted an article about a comparison among the last two ATI Catalyst releases for your own video cards: these are the packages 5.13 and 5.12. The tester used a Athlon 64 X2 4800+ system with a ATI X1800XT 512Mb like graphics card.
The results show the drivers performaces with some games like FarCry as well as Quake 4 are very similar so the main target of Catalyst 5.13 remains the improvement in new ATI AVIVO support (for X1xx boards only).
