That's a hard question to answer 
Personally I'd say that it's no longer BETA. The Config Tool could be more user-friendly but it does work (which is the main thing!).
The bigger deal for me is the lack of 'extra' features that this card was meant to deliver (eg. chunky modes, a 50hz mode and a v-sync option). Another missing feature is native support for the awesome 800x600 SuperPlus mode. It doesn't look like these missing 'extras' will be added to the Config Tool 
I love how often people want to take our money but never deliver on all their promises.
Take my Efika for instance...
