There is pretty much no meaningful performance gain from any additional overclocking headroonm, and the FE/Zotac/Strix all have the same 450w power envelope, so what you are doing is a pointless exercise and yes, dumb. It is classic irrational FOMO.
Pretty sure the FE and Strix can go to 600w?
In any case i'd say other factors are more important. Build quality, fan noise, RGB, warranty, thermals and re-sale value. All important to consider when buying any card.
