Hi alexbrandner,
From my personal experience I humbly advice Palit JetStream. It's silent and very efficient. I play all new games including Crysis3, FarCry4, Dragon Age Inquisition which are stressing GPU kinda hard, and this Palit is just doing all what is built to. Every game runs super smooth on my i5 3570k and 8GB RAM.
All above apply to all GTX 970 cards, but one (very important for me) thing is particular for JetStream - it's super silent.
If you are looking for silent GPU choose Palit, if noise is not your problem - choose anything else (probably Gigabyte).
