I object

You may get some extra performance with cheap hardware & overclocking. Bu that
cheap hardware must have overclocking capabilities.
Btw, I've just upgraded my PSU to
Enermax Infiniti 650W & I'm planning to buy either a
normal Chakra or
Uber version 
Btw, since ATI did not release a R600 card yet, it is not a good idea to upgrade system IMHO
