Yes, I looked at 3090 at that time but the prices were even crazier.
For my XFX 6800XT, I paid only 299€ delta.
I bought it for 999€ and sold Radeon VII for 700€.
If my 6800XT did not get damaged by ESD shock
I would not have bought 6900XTU.
As a matter of fact, I bought first 6800XT Red Devil as replacement for the dead XFX 6800XT, but this sample of 6800XT Red Devil was not good. It did not OC over 2400MHz and even there showed artifacts when running Time Spy.
My XFX 6800XT used to run at 2750MHz@1020mV.
So I was pissed off and got crazy after returning Red Devil and spent damn lot of money on high performing 6900XTU and did not wanted to play silicon lottery by ordering another 6800XT instead of Red Devil.
By the way, I was looking today at what 6900XT Red Devil regular card cost now. It is now 1799€ and it used to cost 1399€ in mid of March. It went up by 300€ since then.
