My 7970 came in yesterday. Only got to play with it for an little while. I can't believe how poorly this card does on POEM. My 5870 beats it easily with the same settings. On the other hand it does a Milkyway task in 43 seconds.
Was also surprised at the lack of any type of manual included. The included disc was useless and way out of date. You know there's a problem when the disc GUI has a PhenomX4 prominently displayed. Then when I tried to register the card on the DMM website all I got were error messages. OK, I'm done ranting but I'm pretty disappointed so far. Hopefully I can tweak it for better POEM results.
