I'd also recommend steering clear of the MSI Armor (gen 1) simply because there's been a lot of issues with PCB sag due to no backplate/reinforcement.
"Loud" is a difficult thing to classify in terms of your question:
One thing you have to consider is the TDP (power draw) of the card you're looking at (a 200W card is going to be more difficult to cool than a 100W card).
Next, look at the cooler itself. The simplest starting point is to count heatpipes. Also, more+larger fans = quieter.
How is your cooling/fan situation in your case?
Then, will you be doing manual voltage adjustments? AMD makes it very easy to do this with their WattMan utility built into their driver software. I lowered my RX480 power draw from 130W to 100W at the same 1305MHz core clock using manual voltages.
I also like AMD's Frame Rate Target Control and Chill features. This also saves a lot of power/heat/noise. I can play lightweight games like CS:GO/LoL/etc with my RX480 fans completely off (passive) because of these features.
