This is more of a: "should you upgrade from a GTX 1070"?
Honestly, this whole "Covid-19" shortage though me (and many others around me) to appreciate the hardwaree I have, ane manage video settings in games. And trust me when I tell you, going from an RTX 2070 to GTX 1070 and then to GTX 1050 Ti (long story), I had no less fun in games. For the first 30 minutes you notices lower quality settings and then you forget about it. Plus when the time comes you will notice an upgrade from the aforementioned GPU, rather than forcing an upgrade for those 50-70% more fps. If you double or triple your framerates, that is an upgrade. Chill and play games for fun and not for the looks.
