I am referring specifically to the 3090 FE at £1399, the MSRP. The OP got one of these not one of the ludicrously overpriced ones. The chance of selling the 3090 FE and then getting a 3080 FE is small and could involve weeks or months of stress which is why I said it's not worth it.are you joking. Have you not heard of depreciation?
As soon as gpus get flooded to the market and if or when the 4 Series GPUs come out, anyone who paid scapled prices will take a huge loss on depreciation!
I.e. pay £2500 for a 3090, in 6months to 1year it will cost £1700 , if those 4 series cards come out, your 3090 will probably cost £1000 and that depends on the price of those 4 series cards. If they are priced similar to the 3 series cards, you would end up loosing 70% of what you paid, so your £2500 card will cost like £750 come resale.
AIB 3080s and 3090s are ludicrous money and are not worth it, even if you can find them in stock.
