I get that, my way of doing it is buying a new GPU when a games I want have been released (like RDR2).
The 970 work perfectly well for me at the moment, one they fix the bug in Dishonored 2 (can't enter full screen at a lower resolution), it will be much better
Cheer, not enough to warrant upgrade, Dishonored 2 is the first games I have play where I have to lower the setting to get it to run smoothly.
