At 1080p (Full HD), the Core i3-540 will hold back the AMD RX Vega 56 by roughly 11-16% depending on the game - CPU-heavy titles will feel it most. The processor cannot feed frames to the GPU fast enough, so you may see lower-than-expected frame rates. Upgrading to a faster CPU would unlock the full potential of your AMD RX Vega 56.
