I agree with him, the 4080 is the absolute minimum for any RT or UE5 game running at 60fps or higher without DLSS and frame-rate trickery on a 1440p 240Hz or 4K 120+Hz monitor. And for some, high resolution, high refresh rate gaming is a thing. The 40x0 series being limited to only DisplayPort 1.4 is pretty bad considering there are now monitors that support full bandwidth DisplayPort 2.1 without compression, it's undeniable that nGreedia has held back the monitor manufacturers from offering faster, higher-resolution monitors. The media also had raised an eyebrow when nGreedia said the 40x0 series was DisplayPort 1.4 only.
Another point he makes is the cost. When you buy an $1200+ card, you expect to max the settings in the game. You shouldn't expect it to give you 35fps in return. The 4080 is too slow for the money, plus some people save for a long time to afford such a card and will expect it to be in their system for 3-5 years. It's an investment, and then to be told you $1200 1 year old card is not only slow in 2025 games, but that amazing new monitor you've been waiting for won't work with you card because it's only DP1.4...
Not everyone uses their computer the same as you or me, you have to respect that.
