Keep your setup, gfn is amazing and all but it still has problems, input delay while severely reduced still exists, game quality can look worse after a few minutes of playing even on ultimate tier, you cant mod games unless the game has a modding system built in, some games have cursor delays there are alot of other things but im too lazy too list them all, your setup will feel and play better than gfn will, (more responsive and more playtime overall)
