I hadn't before, but just did. I took the settings down to bare bones, rolled a pvp char and went for a round of JQ. The game looks a bit.. cartoony.. but I guess that is to be expected. I played just one round, and the fps numbers I got were from 5 fps (heavy fighting) to 14 fps (baby sitting turtles). I hovered around 8-11 fps most of the time. So I could give you a bit closer numbers to what you should expect, I did not overclock, so it ran at 1.6ghz. Here are a few screenshots I took.

I have to say though, I use this card very little, and I just noticed an icon on the system tray saying that the gma gpu is in power saver mode. I get the option to switch it to high performance but for some odd reason it doesn't seem to want to change.. I do believe there are some updated drivers for it, I'll see what I can come up with.
