Good config for msi r9 270x

[realex]

Hi Everyone.

I'm trying to run three r9 270x gpu's on three separate pc's. I'm currently using guiminer (will use cgiminer in my startup folder once I figure out how to setup the .bat file).

1. One of the gpus that I can run almost max load has currently the following settings with about a 450 k/hash rate. Can this be improved with the standard gpu settings (no undervolting/overclocking etc..)

2. The other two gpu's (one each pc) will have to be at a lower usage setting, since I need those pc's to handle my regular everyday work load. What would be good settings so that I can still function with the pc's as well.

I appreciate the help in advance.
