is there a working ati x1600 driver

so you can guess my question already
just installed Vista ultimate 32bit on my iMac core duo in my signature just because i need to use microsoft office 2010 version for windows
, everything works fine , apart from the GPU which is not recognized by windows and replaced with a poxy vga with 16mb


where do i get that driver from as ati's website is more a joke then useful to find a simple driver , i dont need catalyst i want a driver, just a driver that works not more
i am about to get a nervous breakdown and call a shrink

thank you , but still the same result no matter how often i even show windows that ati catalyst thing or how often i let it run windows is totally refusing to see that there is a ati x1600 inside and still using a standard vga driver for a 16mb card
not even on a hackintosh i came across such problems neither on my gaming rig's which obviously run windows natively
or do i think to difficult

update :


YES i did think to difficult , after reinstalling OSX and then windows7 via bootcamp and not even try to install any downloaded drivers windows 7 updated the ati x1600 from alone after running windows update , now even windows 7 is using the native resolution

and windows 7 is actually really speedy compared to snow leopard , can't beat tiger which runs on another partition but still a huge improvent over windows vista which made me switch to linux back then

now i got a real all in one computer.. Mac OS 10.4/Mac OS 10.6/windows 7/LINUX (mint,debian ,fedora,red hat)all on separated partitions and all OSes work natively
