The article suggests that the benches were run at the high power levels already:

60% is really remarkable.
And while it's true that more modern stuff (like Unigine) will tax the drivers more, these naked frame-pushing benchmarks are still important because they show the CPU bottlenecks which are one of the main causes of lower performance.
Obviously, things are improving here. About half a year ago, r600g was slower than 30% of Catalyst, nowadays it's around 75% on some cards/workloads.
With MLAA and VDPAU around the corner, and OpenGL 3.0 almost here, it's a good time for open source.
Uhm... HD6870 is slower than HD5870, but it's much faster than mine HD5870 in nexuiz, that's very strange...
Imho, it's useless if the power/fans aren't working properly.

in my case my 4850x2 sound like a jet plane turbine even on windows so i don't care about it too much and mid power profile is good enough to keep these beast in 60 C wich is very acceptable for me (54C catalyst) beside my phenom II X4 965 BE handle 1080p h264 video using Xv like a champ without killing too much cpu (ffmpeg.mt + vlc)
so i give a damn about UVD and believe or not wine games run very well for me using OSS drivers (stuff like civ5 or lineage2 hi5 or wow ) im not saying it runs at 999fps but as long as i don't get graphic lag is damn good for me (i want to play the darn game not make a race of who get the greater fps in a 85hz monitor lol) and kde4 runs like an work of art in r600g im just addicted to it (no lag, no tear, 100% stable, ridicously fast and responsive, kwin full effects maxed out, etc).
so for my taste and needs r600g is already a piece of heaven for me maybe for you is not there yet but that doesn't mean is useless, so plz show some respect for the many ppl working very hard even when they are so few in the linux graphic stack
what stops the devs from fixing the CPU bottlenecks ????

Lack of time and manpower, mostly.

People like Jerome Glisse have done quite a bit of work at locating such bottlenecks, but it's really hard work, and solutions are not always easy (they might require a redesign, or a different approach).
So it's something that will continue to improve. Luckily, r300g is already so highly optimised, and many of the same tricks can hopefully be applied to r600g with some effort, when somebody finds the time.
UrbanTerror has not removable, permanent 125fps cap.

Overall, urbanterror has terrible bullet physics by the way and it seems to be very cpu bound.
The benchmark must be flawed, unless Michael managed to remove it.
If the game allows you to make benchmarks maybe they remove the fps cap in "benchmark mode"
