My 270x died a few weeks ago so I replaced it with an MSI RX-470 Gaming X 8GB card. It gets close to 30FPS in Assassin's Creed Syndicate on the highest settings running in 1080P. The 270x couldn't hit more than 7FPS under those same conditions. In addition to the new gpu, I have a 2nd HDD that I have 2 partitions. One partition for Windows 8.1 Pro, while the other is for Windows 10 just so I can have DX12 capabilities.
