I have been mining with my R9 390 8gb gaming pc as a hobby for couple of months now. And it has been very profitable for me so far. Where I live electric is cheap, and my currency is constantly losing value against US Dollar (I'm from Turkey, so thanks erdogan lol). I am ready to invest more into my hobby. And turn it into a small invesment.

Please note that, prices here in Turkey are nearly Equal to european prices for cards.

I have figured out what do buy for everything else.

So here is my list;

Intel - Celeron G3930 2.9GHz Dual-Core Processor

Biostar - TB250-BTC ATX LGA1151 Motherboard

G.Skill - Aegis 8GB (1 x 8GB) DDR4-2133 Memory

120GB HI-LEVEL 120GB 2.5 SATA III 550/530 ULTRA

CORSAIR PRO HX-1200 1200W

6 Risers and 1 m.2 Adaptor

At this point I still can't decide what card to buy. I will buy 7 cards.

I have checked whattomine.com and cryptocompare. GTX 1070 looks better for a long run, better at zcash and other altcoins mining. But for a price of GTX 1070 I can buy a RX 580 and a RX 560. Or two RX 570 4gb.

Also Zotac GTX 1070 Minis are relatively cheaper, but I have read mixed comments about those. What is your advice?

Thank you very much all!
