I'm building my first Gaming PC and can't decide between the RX 480 and GTX 1060. The RX 480 has more VRAM while the GTX 1060 has a higher clock speed. I don't know whether more VRAM or higher clock speed is better. I'm going to play games like Far Cry Primal, Doom, GTA V, Rust, Resident Evil 7, Civilization 6, Skyrim, and League of Legends. Any feedback will be much appreciated.
