You'll probably have the best luck with the 4.12 drivers as they were the last decent drivers that ATI put out. Where you may run into problems is with newer games as the 4.12 are about a year old now I think.
That's the ones I use as well. Every time I try the latest set I invariably come back to 4.12 in order to resolve problems (not just AH, but many other games as well).
