@joecrow i am stuck with older series of GPUs due to my HTPC case which i am not going to replace anytime soon, i am using Origen M10 and as a result i cannot obtain any GPU that is not Low Profile, so currently my options are really limited + i feel that new gen GPUs still need time to mature (drivers).
But regarding ur question, it all comes down to how satisfied YOU are! If u like the end results then u should be happy that you got something that pleases your needs. From my own experience i know that the more i fiddle with PQ the more i realize that there is a lot of room for improvement and eventually it becomes a never ending struggle towards perfection and i will be honest here, this process for me has become more pleasant than watching the TV/Movies hehehehe
So it is always up to you
