I'd like to save some money for the next-level card
Also, if it's not the scam, NVidea will give to us, to customers-miners, a new-level card in this August
Hope for it, really
Also it'll be perfect for different complex modelling
A new series of video cards will be expensive in the first months. Another problem is the software for mining. Developers will have to optimize the software for mining on new chips. This also takes time.
Asics, FPGA very quickly reduce the profit on the GPU.
If I were investing in mining, I would do it now
