Yeah coin values being so low and GPU prices having skyrocketed in the last month are looking to render GPU mining non-viable pretty soon I think.
The next batch of Vegas has landed at some suppliers and they have obviously been watching what they were selling for on ebay, since they are now charging over £900

When Ainars and I bought them last year they were £400! At the new price that's an ROI of 3 years, and that's assuming BTC's death-spiral ends fairly soon.
My Amazon Vegas were supposed to land next week, but they've just been pushed back another month. Extrapolate the graphs and by the time they get here it'll barely be worth mining with them
What's the A3 doing at the moment?
