Honestly, its a bit of a toss-up and unfortunately neither choice feels perfect for $800 right now. I tried the NVIDIA GeForce RTX 4070 Ti Super 16GB GDDR6X thinking the newer architecture would save me, but I actually had issues with it stuttering on heavy 4K timelines once I started piling on the effects. That 16GB buffer is just... not as good as expected when you're doing professional client work and need to keep everything in memory. It feels like Nvidia is being super stingy with VRAM lately which makes life harder for editors. If youre strictly editing in Premiere, that 24GB on a used EVGA GeForce RTX 3090 FTW3 Ultra 24GB is basically the gold standard, but the power draw is insane and really jacks up the hidden costs. I had to upgrade my PSU just to keep mine from crashing, which sucked for the budget. Finding one for under $800 thats not been mined to death is also getting harder these days. If you can find a clean 3090 from a reputable seller, grab it. The extra VRAM is the only thing that actually stops those annoying Out of Video Memory errors when youre pushing heavy 4K exports. If you absolutely have to buy new though, the ASUS TUF Gaming GeForce RTX 4070 Ti Super 16GB is probably your best bet even if it feels slightly underpowered for those of us doing this for a living. Just keep an eye on your background apps because Premiere eats VRAM like crazy.
