At 1080p (Full HD), the Intel Celeron G6900 will hold back the NVIDIA GTX 1660 by roughly 11-15% 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 NVIDIA GTX 1660.
