Been using my pc for mining but would like to add more cards so i'm looking for the best option without building a dedicated mining rig.
Current PC spec.
I5 7600k ( i have been downclocking it when mining)
Gigabyte Z270 HD3P - https://www.gigabyte.com/Motherboard/GA-Z270-HD3P-rev-10#kf
EVGA GTX 1080 FTW
x1 16GB ram
80% gold EVGA 750w suprnova power supply (if i add more cards i can change this)
If I sold my 1080 i would not lose a lot of money if any with the current prices on ebay as i received cashback on it.
Am i best selling it and getting two 1070s with the option to add more as i go?
Can I keep my 1080 and add a 1070 or two without using SLI and so when i game it uses just the 1080?
Am i right in saying my motherboard supports 4 cards?
Any advice much appreciated
