my justification is because my 4090 is worth so much on the 2nd hand market the difference between paying for a 5090 and selling my 4090 is minimal. if I had to buy a 5090 outright i wouldn't do it.You need to question your life choices when you are happy to hand over up to £3K now for a GPU that may arrive at 'some' distant point in the future. The stock is clearly not available, gamers are NOT NVIDIAs priority, and the 5080 is laughable in terms of some of the prices being 'offered'.
What a sad state of affairs, and FOMO is enabling this continued behaviour from a multi-trillion supplier who must be laughing their ******* off. Get a grip.
