Obviously it sounds like the card is FASTER and HOTTER than the current gen, but it also seems like you probably don't need to worry about upgrading unless you're in the market for 4K gaming (assuming you're already at the 3xxx level).
I have a 3080 right now and I'm pretty happy with it at 3440x1440 resolution. I'd be in the market for a new souped-up card, but with the size of these things, that basically means I need a whole new computer before I can consider buying one, or at least a new PSU. That'd be expensive!
In pure rasterized games, the NVIDIA GeForce RTX 4090 is 100% faster than the NVIDIA GeForce RTX 3080. This is something that NVIDIA hinted at its Overwatch 2 benchmarks. And yes, we can confirm that the RTX 4090 is a rasterized beast.
Cool! I could use 100% more framerate at some point. But I think the bigger gripe I've seen is that there really aren't a lot of high-end AAA shiny-ass-graphics games coming out right now that are going to drive people towards these cards. There hasn't been a better-looking game to hit since Cyberpunk launched, and that game is almost two years old. When we get out of the COVID delay season, maybe that'll change, but we really need a new DOOM or something before I'm going to pony up for a new system.
