What is the best GPU for 4K video editing in Premiere Pro?

Question

Ive been cutting video for like eight years now and usually I can troubleshoot my own rigs but Premiere is just killing me lately. I just started taking on more high-end wedding work here in Chicago and the 10-bit 4:2:2 footage from my new Sony is absolutely wrecking my timeline. My old RTX 2060 used to be a beast for 1080p and basic 4K but now even with proxies it feels like Im editing through mud and the export times are just laughable. Like I left a 10 minute sequence to render last night and it crashed halfway through because of some GPU acceleration error that I cant seem to shake.

I need to upgrade like yesterday because I have a massive delivery due next Friday and I cant keep working like this. I have about 800 bucks to spend maybe a little more if it actually makes a difference but I keep seeing conflicting stuff about vram vs clock speed for hardware decoding. Should I be looking at the 4070 Ti Super for the extra vram or is a used 3090 actually better for how Premiere handles the Mercury Engine these days? Honestly just need the most stable option that wont choke when I start layering Lumetri effects on top of 4K clips. What are you guys actually using that doesnt crash every twenty minutes?

Catching up on this... I totally agree that VRAM is the real bottleneck here. Honestly tho, I was pretty disappointed with the cooling on some cheaper 40-series cards. For long wedding renders, I'd grab the ASUS TUF Gaming GeForce RTX 4070 Ti Super 16GB. Unfortunately, those cheaper dual-fan models just thermal throttle and crash. Its worth the extra eighty bucks for the three-fan setup and better VRMs to stop those export errors.

To add to the point above: i actually think the 40-series is a better bet than a used 3090. While the 3090 has more vram, the dual encoders on something like the NVIDIA GeForce RTX 4070 Ti Super 16GB are absolute lifesavers for those long wedding renders. Quick tip tho: make sure hardware decoding is actually enabled in preferences for h.264/h.265... premiere sometimes acts weird with sony 10-bit footage if that isnt toggled right.

I ran into this exact wall when I moved from 8-bit to 10-bit Sony footage last year. I wasted so much time troubleshooting those GPU acceleration crashes until I realized my old card was just choking on the VRAM buffer during long renders. I ended up picking up the NVIDIA GeForce RTX 4070 Ti Super 16GB GDDR6X and the difference in the Mercury Playback Engine was night and day. Even with three or four layers of Lumetri and some light grain, the 16GB of VRAM kept everything stable without the timeline stuttering like crazy. While a used NVIDIA GeForce RTX 3090 24GB GDDR6X is a beast for raw capacity, the newer architecture on the 40-series feels more optimized for modern HEVC codecs. Quick tip: always swap over to the NVIDIA Studio Drivers instead of the Game Ready ones; it basically stopped all my random Premiere crashes overnight.
