Powercolor cards are good, but as T2bus said, their customer support is terrible. I'd even go as far as to say it is non-existent. I haven't had much fun with gigabyte either, they took 2 months to get back to an email of mine apologising for the delay and not even answering my question. I'd completely forgotten I even emailed them by then. But that is just my bad luck I guess, others probably love Gigabyte's customer support.
