I've been looking into getting a new graphics card for a while now but right now the prices are inflated quite a bit. As a result I have been looking at the used market to get a GPU that will last until prices come down. I found a AMD reference card R9 285X, Asus Strix R9 285, Gigabyte Windforce R9 285 and a MSI twin frozr R9 280x. But the thing is older generations AMD GPU's tend to run hot so which one is cooler and quieter? Note: Right now I use a Asus Strix GTX 950.
