You can sign me up for beta

got a 4850X2 (dual gpu card) im willing to throw at it

Also i have another suggestion: Add different logging capabilities like logging the mhash/s every x second, temperatur and fan speed logging would be nice too but it might be a hassle if you want to support Nvidia and AMD...
If you follow up on the GUI request it might be nice to add graphs for the logs that opens in a new windo aswell but the primary idea was to log them to a txt file so they could be read by a seperate program if need be
Im pretty sure temperature and fan output would be very hard to make portable across gpu / os. I think we're going to have to use a separate monitor for those.
Thanks for the input, ill add you to the beta.
