The card is clocked at 1 Ghz by default?, and they easily added and extra 125 Mhz without even needing a voltage bump?....That's 200Mhz extra over a stock clocked HD7970 card, wich is clocked at 925Mhz:

It's the kind of clock speeds that can't be done on a GTX580 without a voltage increase first of all, and not exactly recommended while still air cooled....
