So I answered your question, no current all-in-ones have good 3D performance. Some are decent for low end stuff, but they all carry mobile graphics processors. The best i've seen was a 9600M GS, which Nvidia has been getting a load of crap for re-badgeing their old mobile series, and having performance issues with them...
So, I did answer at least part of your question.
