I thought about 1050's aswell as i already own a 1050 ti and was able to test it and i also liked the idea of less pcie 6/8 pin plugs as this is the common shortage of all PSUs.
Here is why i went for 2 1070s instead:
-1050 2GB wont mine Ethereum, 1050 ti (4GB) is just a pain to reach any payout limits on any pool and also nicehash miner doesn't seem to like it (benchmark crashes).
-My Zotac 1050 ti only gets 2.5 Sol/W on ZEC
-It draws 75W through the PCIe slot (mainboard). I believe thats the reason why it also is not SLI Capable...you can definitely NOT pull 3,4,5 or 6 * 75W through your mainboard, it will melt...i wouldnt put more than 1 1050 per mainboard.
-Over/Underclocking is very limited (70% - 100% TDP only)...though my card reaches +650mem easy
If you really want to do this, check specifications of how much power you can draw on all PCIe slots together (I didnt check) but im sure it wont support 300W.
Cheers
Really good reply, thank you.
I like the idea of going for less cards and going for the 1070+ cards too. Can always add more 1070's later
Also, the 3 fan 1070 cards do look amazing imo.
My planned rig builds is in very early stages, i wanna plan it, no rushing into ordering loads and getting the wrong setup.
