I've been researching for the past 5 months trying to find a GPU that would be a viable upgrade from my current RX 6600. It's a lot of money to spend for me personally, so I don't wanna pay for the stuff I don't need.

I have boiled it down to 4 GPUs:

RX 6800 XT
~$880-900 AUD new
~$750 AUD used
~$650 AUD used and mined

RTX 3080 10GB
~$700-900 AUD used

RTX 3080 Ti
$850 AUD used/refurbished

RTX 4070
$900-950 AUD new

I won't have any problems with dimensions, nor shouldn't have any wattage problems as I have a 850w 80+ Gold PSU. The RX 6600 I have right now sits around 35-40c idle with fans spinning, and around 70c playing games. So I believe temps shouldn't be too much of a problem.

I have two monitors, a 1440p as my main one and a 1080p off to the side, both running at 144Hz.

I mainly use my PC for gaming, I don't play the newest games but I like to have visual clarity while playing them, so I increase resolution and textures, which intern uses up more VRAM.
I use Adobe Photoshop and Premiere Pro, I have already use my RX 6600 for editing and personally have had little to no problems.
I also play VR games, I heard that Nvidia's GPUs are more reliable for VR, however using my RX6600 I don't have much problems other than low performance obviously.
I don't record myself gaming much, but like to have an instant replay thing ready to go, like Shadowplay.

The rest of my PC specs:
+1 RX 6800 XT new

However, RX 6600 is still decent enough to last until the market improves. I'm not sure IF the market will improve anytime soon. The next-gen of GPUs are not any better and are actually worse in a lot of regards.

Again, +1 for RX 6800 XT new.

That, or the RX 4070 is one of the more likeable GPUs from RX 40 series except for its price. If it had 256-Bit memory bus and 16GB vRAM at the same $599 USD it would be a perfect GPU.
If you have money then buy new GPU and not used one and 4070 is abit faster then RX 6800 XT
Same settings the RX 6800 XT is more often faster than the RX 4070. With more vram and at the same price, it will have a longer life without losing performance due to vRAM limitations.

DLSS3 does not count for me, because I am not a fan of increasing latency with the advantage of fake frame generation. I'm not sure who in their right mind would have thought gamers would be interested in that at all, let alone paying more for it.
Consider the possibility that your cpu may not be strong enough to take advantage of a big jump in gpu capability.

Try this simple test:

Run YOUR games, but lower your resolution and eye candy.
This makes the graphics card loaf a bit.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

New vs. used is a perennial question.
My thought:
If you do not have the money, only buy new.
You can't afford a bad purchase.
