So I just bought and Sapphire RX460 4GB OC and it sucks. My performance is really low. I have around 40 fps with everything down in CS:GO or The Witcher 2. I installed it without having installed any another graphics card before so I didn't uninstall any driver. My PC has this specs: Asus fm2a88m-le
8GB RAM Kingston hyper x 1600 CL11
A kingston SSD, i don't remember.
Without the graphics card, I had higher fps so, any idea?
