I recently bought a 5070 because I was excited for the upgrade and I really like DLSS. However, I came across a sale for a 9070 XT that's now the same price as my 5070. The catch is that while the 5070 works perfectly with my 650W PSU, I believe the 9070 XT requires a 750W PSU. I'm torn about whether the performance increase is worth the extra cost of upgrading the PSU. Additionally, I'm concerned about FSR and whether the 9070 XT will receive as many updates as Nvidia cards do, especially given that some games have limited native FSR support compared to DLSS. What do you think?

Switching to the 9070 XT is a smart move, just remember to upgrade your PSU. Better safe than sorry with wattage.
If you're gaming at 1440p, the 9070 XT should easily crush games at max settings without needing FSR. Plus, FSR support is really expanding, so you’ll see more games benefiting from it down the line. A new 850W PSU isn’t a huge investment either for that performance jump. Just make sure to ask yourself if you truly need that extra power right now.
Honestly, if you don’t really need the Nvidia features, going with the AMD card makes sense. The 5070 is a decent card, but the 9070 XT gives a better bang for the buck.
The 9070 XT might actually work fine with a 650W PSU depending on your setup. You could even try a slight undervolt and power limit to make it work. The performance boost is around 25% with 4GB more VRAM, but whether it's worth the effort really depends on your personal needs.
Upgrading gives you more headroom for any future upgrades though. If you can swing it, bumping to at least 800W could save you from stressing your PSU.
Definitely worth upgrading for the extra VRAM. If you’re playing demanding games, that’ll be a game-changer for performance.

I ran my 9070 XT on a 550W PSU without issues for months, just with a modest undervolt. It can handle spikes well, so it’s doable if you keep an eye on it.
