As I mentioned a few posts previously, I ended up buying a RX 6800 XT.
My reasoning was this:
Eliminated
Rtx 3090 just way too expensive. Retail prices are around £2500, minimum, theses days for a 3090. Yes, they are available but that is just way too much money for a graphics card.
An obscene amount, if you ask me.
Eliminated
Rtx 3080 and 3080 TI which are also way overpriced in this market. £1400 if your very lucky. Realistically £1800 for a quick purchase. Yes, I could wait and wait and wait to see if I could get hold of an FE. An FE would have been my first choice. But, it is unlikely I'd manage to snag one.
Eliminated
Amd Rx 6900 XT. Yes, it's a better card than the one I ended up choosing but price/performance ratio didn't justify me spending five or 6 hundred pounds to get 11%, or so, performance increase.
I'm not an avid gamer. I enjoy sim racing .Well, to be honest, it's nearer arcade racing. My skills are just terrible. But it's fun. I don't play much in the way of other games.
So if I wanted a decent graphics card (And it would have to be decent, as I use it for VR) then that leaves me with the Rx 6800 XT. Cost me £1000.
Thank you, everyone, for your input. It really helped me decide.
