I went pretty low budget on this, all from ebay. I decided to go with GTX 1050 2GB gpus because they seem to have the best price to performance. I grabbed the cheapest 5 on ebay at the time from 130-150 a pop, a biostar 6 gpu mining motherboard, celeron g3930, a 4gb stick of ddr4, 60gb ssd, and a 750w evga psu. Total cost was just over 1k. Not bad by my calculations this puppy will get 750 sol/s on zcash, netting 140 a month. Just over 3 month roi seems quite solid, then its pure profit. and this is on top of the fact that im now mining my 1080 in my gaming rig whenever im not gaming and my 1060 in my laptop as well when its not in use.
With the current prices I guess 1050 2gb is not a bad choice , Your other option was to wait for the prices to get back to normal . So I guess getting this card might be good start at the moment . I strongly advice to not mine on your laptop . Finally good luck with your cards and happy earnings
