Seriously every time I update my ATI drivers I end up spending 2 days fixing all the things that went wrong because of it. You think I'd have learned by now, I've been using their crap since 2005. Next time I'm going with Nvida.
Well for mining ATI ones are the best ones... with nvidia you will be looking into half performance (using CUDA vs Open CL) I bet at least half of the sales of ATI are thanks to cryptocurrenties :p
