2D looks the same to me accelerated or not. Maybe there is some difference, but I never notice it either. Run a 3D GL application and you should notice a big difference then. Video playback may be influenced by drivers too. I haven't done enough testing to see where the differences happen, I just know there are differences depending on software configurations.

What I've read about ATI and what I've personally experienced are often three different things. Enough that I'm a bit gun shy around the stuff anymore to the point of avoiding it. I am still interested in others experiences with ATI though, to see how they compare to mine.
I mean if I hear enough favorable I might give their stuff another try.
I did notice one odd thing with my Intel machine. Theoretically acceleration was supposed to work on Lenny but I tried it and the X driver and the kernel driver never quite communicated like they were supposed to. What I read said it was supported and should work, but it didn't work for me until I upgraded to Squeeze, which has a newer X, then it all worked as it should. So it wasn't me, I can obviously configure the software. Being as I managed to get it to work in Squeeze, but the same thing didn't work in Lenny.
Although everything I read said it should have worked. Sometimes the truth is in the testing though.
