"Beating" or winning to me is which configuration offers the smoothest gaming experience at 1920x1200 with AA active. I couldn't care less if my rig beats another by 15FPS in averages if I'm getting hard hitching too often. Xion made a good point, bar graph reported FPS certainly does not tell the whole story.
I sent one of my 5870s back to ZZF for a refund, the other was sold, and a third has been dropped in my alt rig.
"Winning" benches and getting high e-peens are great and not at the expense of surrendering smooth game play at 1920x1200 with AA active in demanding titles. Honestly who plays 1280x with medium textures and no AA? (Hi Vantage performance
This 470 @ 1483 shader is very fast and more importantly smooth with AA at the res I play. If I feel I need more for whatever the reason, I'll get another.
I don't know what's helping this card out vs the 5870 with keeping AA smooth in STALKER CoP @ 1920x1200; greater memory interface size, +280 ram, or drivers. Perhaps all three.
On a side note, I recently tried a neighbor's 3d vision set up and liked it a lot. I've got an Acer GD235HZ and the 3d kit incoming to run that.
I'll likely go missing from these sort of forums soon because I will be off gaming
