I've been giving the open driver an extended try for the past few days on my 5770 for the first time. My results are nearly identical to these results for the 5750 except that not only does dynpm not adjust itself properly (keeping itself never lower than the same frequencies of the mid profile) but it also creates very noticeable blinking of the screen whenever it does switch. I keep it in the mid profile mostly, which is just fine for everything short of playing games, or other significant 3d rendering. I just wanted to point out, however, that using this driver is a far better experience than catalyst for, again, everything other than gaming. I can actually scroll on chromium with it maximized with out any lagging (more than I can say for the catalyst driver with tear free on) or tearing (again more than I can say for catalyst). All video playback is perfect as well. I seriously hope someone works on getting dynpm to a useful state soon, because as soon as that works, without question I prefer the open drivers after using them a few days. The only bother I have is using the mid profile keeps me at a steady 55C, which isn't awful, but the fan noise really does kill me. Thats compared to somewhere in the mid 40's while using catalyst....Also unity and the new compiz in natty work much much better on the open stack. Using catalyst gives a much more jerky experience, plus the mouse corner lag bug in 11.5, and 11.6
