I bought an asus turbo oc graphics card which was very noisy, and my supplier has agreed to replace it for me for any of the other gtx970's, my question for you guys, is which one i should get. things to note: my case doesn't have the best airflow, the asus turbo got to 80 degrees under load and around 35 idle. my power supply is 620w, and noise levels matter a lot to me. from what i heard, i should either get the msi, the gigabyte g1 gaming or the asus strix. which one of those should i get if the cost is not a factor?
