Yeah a lot depends on price. I got the 1 aorus 719 and tax at newegg = 780 I have been running it since early april it earns back nicely.
But I got those msi aero's under 600 they are good and 183 usd is a big price difference.
To be fair if I used the ebay sale for an aorus it would have been 780 - 57 in ebucks or 723
still 723 vs 597 it was an easy choice to get the msi..
also it is summer I get heat capped so I am gentle on my cards 65-73% tdp keeps stuff cool and saves power.
So the aorus pushed has a bigger tdp.
I guess I am saying your setup matters a lot. I don't see me running 20 aorus 1080 ti's this winter.
But 20 msi aero and Founder cards this winter look possible to me
