So happy I got this card. Creams through every game I played. Also, just on a side note, I was playing around with this card and realized that it can be overclocked out of its limits even without the sapphire trixx utility, using the latest catalyst driver and aticonfig from command line. Mine successfully runs at 910(coreclock)/1475(memoryclock), which is pretty amazing for a 6950.
Edit: Also, phoronix got the specs wrong. The default clocks are 800/1250, not 800/5000.
