yup, agree... however, this article is more for ppl considering to buy some GPUs for mining now... we should count in the order, shipping, etc. and Vega will be out end of July. This should already project on the current 10xx series prices. If the price will drop by €50 and you can get more powerfull card for less, you might end up in better profit considering for example 6months window. The ROI on 1070 is still very nice - no doubt about that :) I'm more talking about what is a better investment - now 1070 for €430, or wait one month and get it cheaper, or get a better performing GPU.
