So I put the 5570 into my Windows machine. Strange thing is that on the dedicated Linux machine, with a faster CPU and newish mainboard, it was getting a max of about 61Mhash/sec... but now in the windows machine, with a slower CPU and older mainboard, it's getting 69Mhash/sec. WTF? Maybe it's a driver thing...

I upgraded guiminer to latest newer version which has Phoenix miner integrated which allows to set flag such as BFI_INT VECTORS AGGRESSION=12 -k phatk (i use aggression=8 because my cards perform unstable at 12) huge improvement in hashing rate with the same gpu settings, I was doing 500-510MH/s before upgrade and now they are crunching 550 stable. over 10% improvement in hashing rate!
find guiminer thread and at the end of OP there is a link to instructions how to use it with phoenix phatk miner if you haven't done so
