I got my 5700XT for $300 and I'm currently running a 1440p @144Hz "gaming monitor". 95% of games are not significantly subjectively improved by upgrading to 3080, given this monitor. But, reviews had me convinced that Ray Tracing was finally worth having w/Cyberpunk 2077, and, I wanted to experience what gaming at a steady 144Hz was like.
Ray Tracing maybe "cool" in CP77, but, once I start
playing (rather than taking a break to just look around) I stop noticing the improvements brought by it.
...However, all that with massive power consumption...
Aside from the $809 price (of the FTW3 Ultra, which is the cheapest I could find in stock), the power consumption was the hardest aspect for me to swallow - if I hadn't read about undervolting, I don't think I could keep this card.
I hope they add excellent undervolting support to Precision X as MSI Afterburner doesn't seem to 100% work w/EVGA's 3rd fan. Also, Afterburner's "Voltage Curve" editor is unintuitive to me, I think they got the Mhz/Voltage axises backwards and it's not clear to me how to set the voltage for very low speeds, such as when you're just doing light 2d work like web browsing.
