While the reply about your system handling it no problems is mostly correct, the older architecture and lower clock speeds of the 4770 will limit performance to some degree, especially on lower resolution/higher frame rate of say a 1080p 144Hz monitor. Ironically, at 1440p or 4K the load is shifted from the CPU to the GPU.
I've got a GTX 1060 6GB and even it gives better performance now that I've overclocked my i7-4790K from 4.4 to 4.8GHz.
