One thing we must remember is these GPU manufacturers have to sell stuff to make profits.
The difference is going to be minimal between monthly releases of these GPU's
The only way you will see a real difference is over a 12 month span or completely renewing your PC every time a new GPU comes out with the latest and fastest everything
I am pressurized into holding stock from manufacturers on sale or return these days as they know there's too many products out there and the market is swamped with out of date motherboards CPU's and GPU's too much for smaller business like mine to hold stock out of my own pocket as its all redundant after 3 months some times.
Don't let the hype confuse you into buying ..................
