Video card upgrades
A question that comes up often on the boards is upgrading a video card, without upgrading the processor.
Take a look here for an extensive test of CPU's and video cards, that shows just how much CPU performance can hinder GPU performance.
This is why I usually recommend upgrading the whole machine rather than slapping a better video card in it.

the table above shows a good match btn cpu and gpu. there is significant speed up of fps at 4k every 2-3 years, justifying the super expensive cost of each combo going to Intel and Nvidia coffer.
the point of article and OP is if you do not match cpu w gpu and you upgrade gpu first while staying on outdated cpu platform, there will be some performance hold back of the super fast new gpu. But it may be minor.
example,
a drop from 156 fps at 4k.
this shows you do not have to upgrade to 13gen to match 4080. the 11th gen in AW R11 seems ok for now.
another example
down from 106 fps. that seems tolerable.
this seems to say a little mismatch is ok, a glaring mismatch is probably bad idea. here is a bad example
down from 152 that you would have got if you upgraded cpu to 11-13th. go figure.
