When I was parts picking a graphics card for my current PC , I knew I wanted a strong 4k card. The 4090 was certainly that, but the power consumption was daunting, and the price / availability was terrible - over $2000 was just a bridge too far!
Despite the reviews on the 4080 wailing about the value, I selected it because it met my goals better than the alternatives, and I got it at Nvidia MSRP (a rarity at the time). ATM you can get a 4090 for $1,599.99. If I was buying now, I would have to chew on it, but would be tempted. Meanwhile I am happy chugging along with good frame rates in AAA titles at 4k.
