GTX 1060 is probably much more powerful while costing only $50(?) more. GTX 1050 is also coming soon, might become the best mining GPU.
yeah, another good reason to avoid 970 right now, i really see no point in it anymore
but i would not buy 1050, you would lose a good portion in density if you want to go big
i presume that if right now the ration is 4:3(4 rig of 1060 = 3 rig of 1070)between 1060 and 1070, with the 1050, will be 5:3 or 2:1
The 1060 costs 100€ more. That's than 40% more or maybe even more. Well, the Palit (not a big brand), is "only" 70€ more. Does the 1060 produces 40% more daily ? That would be the only reason for me to legitimate it.
However, the 1060 uses less alimentation connectors, so that's a really good point.
Edit : those prices were too good to be true. The 349€ Strix will be available in 2 to 3 weeks and the Gainward at the same price come with 20€ of shipping and such... No, the 970 is widely available and sold at its right price. I'm also thinking about the GTX 950 for its low price, that come to the price of a low density. For some reason, I should prefer low-priced GPUs (I can explain you in PM if you want).
Edit II : looking at another site, I can get a Palit at 319€. All what I need to know is if it is good or not. I'll surely have to convert my bitcoins in PayPal money though.
