Dunno what to tell you friend. Both alternatives are viable but obviously you aren't happy with your ue5 performance so why wait sell and get a 9070xt which is what? 50% faster? 30% faster? Better AI upscaling at least natively.

If "runs bad at native" means "I want 1440p or 4K at very high settings and every single frame to be below 8 ms" then of course, because most hardware won't do that in those games (and some of those dropped frames are game/CPU side regardless of the GPU anyway).

I've been pretty happy with my 7800 XT in the Unreal Engine 5 games I've played, but my resolution and frame rate target isn't crazy high either.

I don't think it's financially worthwhile to go from one generation to the next at the same tier, but if you're desperate for any improvement and can't afford better, then I suppose it's better than nothing. I think the next generation would be the most worthwhile (or realistically, two after) since the upcoming consoles are going to be based on that most likely, but those are a ways off. Then again, a 7800 XT can last as long unless you absolutely need more right now. And that's your choice to make.

If you do decide to upgrade, I'd consider giving the RTX 5070/Ti a look because while you'll still need upscaling with them, you also would with the 9070 XT, and while AMD has better upscaling with FSR4 (than FSR3), nVidia is still a bit better there (not just in quality but in games supporting it, but there's probably manual ways to inject FSR4 into unsupported games if you don't mind the extra effort).

NO! Not worth it.

7800XT is fine, not worth losing $400 for FSR4 and minor bump.

If you're not happy with your 7800XT, then a 9070XT isn't going to help in my opinion.

It's faster and has better upscaling but you dont get any extra vram with the upgrade. Feels kinda lame because of that. Better feature set but if that's what you're after you might as well go RTX.

I'm with the good folks here.
I don’t see any reason to upgrade from a 7800 XT to a 9070 XT, same team, same features, and only a small FPS bump. You could get around 300 to 400 bucks for your used GPU, depending where you live.

If you want to move to Team Green though, like a 5070 Ti or 5080, then yeah it could be worth it ,especially if you can get a cheap MSRP card like an INNO3D or such.

You’d get better RayTracing support, superior upscaling technology, stronger office/professional support (CUDA cores for video encoding, deep learning, etc.), improved AI features, less heat (which keeps the rest of your hardware cooler), and lower power consumption. I’m sure there are more upsides, but this should do for starters.

Either switch teams or wait for the next generation.

Depends of the selling price of the old GPU.
Waiting for the next gen will make the new GPU a better value (probably) but the old one will likely sell for less.
So selling now is not the worst idea. FSR4 is worth the jump when FSR3 is so bad and FSR4 on rdna3 runs a lot slower.

On a side note: try TSR in UE5 games. Not perfect but better than atrocious FSR3 for me.

according the reviews the 9070XT is as good as the 5070Ti and in some games almost as good as 5080 and its vastly better than the 7800XT in ray tracing
