SC GAMING ACX 3.0 Black Edition, 08G-P4-5173-KR, 8GB GDDR5, LED, DX12 OSD Support (PXOC)
$579 - EVGA GeForce GTX 1070
FTW GAMING ACX 3.0, 08G-P4-6276-KR, 8GB GDDR5, RGB LED, 10CM FAN,
Thank you

I use FTWs but be careful not let them overheat. If you can, align them vertically or in parallel, but be careful with vertical stacking as the heat from the lower card(s) will rise and overheat the upper card(s). I had one go up in flames after two months or so of mining. Also be sure to give them time to rest and cool down from time to time. Learnt my lesson the hard way.
