If you have the bandwidth you should be alright. I've been with GFN since their beta and imo cloud gaming (as gamer) beats following the GPU arms race every other year.

Pro tip, make sure your native display resolution is actually set in the custom GFN connection settings and enable v-sync in the client. Also consider disabling automatic resolution scaling. Slight latency spikes can make your game look blurry and it takes forever to upscale again by itself.
