The 4090 is good enough for the next two years.buyers remorse will go fast
thats what made it easier for me, sold my 4090 otherwise no way would I have bought a 5090 at full RRP, been upgrading since the 20 series so selling before the new release and you can get back most of the money, I think this is the only time I had to pay a bit more cash, but you have a 5090 now and your covered for the next 2 years
