@robinl: What about the sync-to-vsync setting in CompizConfig Settings Manager (AKA ccsm)? As already reported by other users, this seems to be the main problem leading to poor compositor frame rates on Ubuntu 11.04 with fglrx, regardless of raw hardware performance.
Some users with low end or integrated graphics are still experiencing lag even with sync-to-vsync disabled in ccsm. See Nick's report above for example. That's why I was suggesting to try the other vsync and tear-free options in the Catalyst Control Center. You have a fairly powerful discrete graphics card, so I would not expect your system to be affected by long lag as reported by Nick.
