I was thinking though, what about the future GPUs coming out? Surely with the way technology has progressed thus far, within a few years we will have GPUs pumping out 10x the current output of any current day top of line cards.
I whole-heartedly believe that unless you have any dedicated, full-fledged multi network mining rigs, you aren't going to make any decent profit in the future.
Sadly though, my knowledge over the subject is trivial compared to many other memebrs. I could just be spewing pure BS.
