Any recent radeon hardware supports multiple monitors just fine with
the caveat that if you are using more than 2 non-displayport monitors,
they have to all use the same clock (you are limited to two
independent clocks), or you need active dp adapters.  If all of the
monitors are identical, it shouldn't be a problem.
