TweakTown posted an ATI Catalyst 5.12 Performance Analysis (X1K Edition)

It seems like this is an early Christmas present to those Radeon X1800 users. While we thought the performance from the X850XT was good with the new drivers, we can see that the X1800XT gets more performance and almost across all our benchmarks. Quake 4 again gave us some weird results with the performance being slightly decreased at 1024 x 768 but apart from that the drivers get two big thumbs up from us.
