These ATI tray tools where do you find them? Is it better or about as good as Trixx?

I found them here.

So my rigs are very clean, nothing but Win7x64, ATI drivers and AMD APP SDK Runtime. Then I turn off UAC and install ATI Tray Tools. Then make sure on the Hardware Overclocking you turn up the voltage to 1.163 and hit apply before you start moving the sliders. On my HD 5830 I am stable at Core 1001 and Mem Speed 300, temps stay around 70 to 72 but I do have moderate airflow.

After you get it all dial in and stable you should make a profile by checking the "Include clocks in profile" then clicking save icon. You can then select that profile to load on startup. With this method I am getting 303 MHash/s running Phoenix/phatk with these options:
-k phatk PLATFORM=0 DEVICE=1 VECTORS BFI_INT FASTLOOP=false WORKSIZE=128 AGGRESSION=12

I know other people are getting more, but this is what is stable and has the most yield for me at this time. (And I am way happy with 303 MHash/s as compared to my 6970s which cost like >$200 over the 5830s and barely get 78 MHash/s more...)

The question I have is does anyone know of a OC'ing tool that will handle multiple GPUs?
