The cheapest you can find.
Generally I agree with this especially if you find a killer deal on one.The hybrid EVGA models are nice for good clock speeds and temps without generating a lot of noise. Can be spendy.
Founders Edition cards are OK though if they are in a warm case they can be very noisy with the blower fan spun up. I sold mine for that reason.
My aorus and evga sc2 hybrid are nearly silent. The aorus (and strix) are huge cards. If you are putting these inside a case the motherboard slot spacing has to be considered. Two giant cards next to each other means one is going to get choked for air.
