I play race with like 200fps but when turning on antialising the game throws me out after a few seconds.......or more right steam does, telling me something is wrong.....why???? plz can anyone help me out here?
That's true, though the discussions in the forums are going into the direction that Vista is actually the problem, but who knows...Surprised the drivers haven't matured a bit more from Ati's point of view, a fix or something, Vista has been out quite some time now.
Good luck anyway.
I am not using any overclocking.I think you should uninstall all drivers, then run driver cleaner, can be found on Guru3d.com. Reboot without the drivers and install the latest driver.
Then update the directx files to the latest, see this threat:

Do not use any oveclocking tools you get with the motherboard, only overclock by setting some settings in the bios.
