27 is what i see people hitting with 470s after BIOS modding, seems 480s do 28-29ish.  It's kind of hard to tell for reference purposes reading threads here because it's not always clear exactly what model someone has and/or what mods they've done, plus I'm sure some is bragging about winning the ASIC lottery.

Anyway, I wanted to make sure i'm clocking in the right neighborhood since I've seen my total shares dropping while the profitability is through the roof, just wondering how much more I could push them realistically without spinning up more rigs.
