So i get why your stuck on this, but for your situation, I would suggest the NVIDIA GeForce RTX 4080 Super 16GB as the absolute best value pick. It usually retails around $999, which is way more reasonable than the NVIDIA GeForce RTX 4090 24GB that is still sitting at like $1,700 or more right now.

• The 16GB VRAM on the 4080 Super is actually plenty for 4K 60fps timelines in Resolve, even with heavy grading and some noise reduction.
• Nvidia CUDA cores are basically industry standard for those AI denoise tools; AMD cards like the AMD Radeon RX 7900 XTX 24GB have more VRAM for around $930, but they kinda lack the same driver stability in Premiere Pro.
• I would suggest looking at the ASUS TUF Gaming GeForce RTX 4080 Super 16GB GDDR6X specifically because it has killer cooling for those long export sessions. Basically, dont spend that extra $700 plus unless you literally do this for a living 80 hours a week. The 4080 Super handles 4K workflows like a champ and saves you a ton of cash. gl!

I remember trying to edit 4K 60fps on a card with low memory and it was basically impossible once I added noise reduction. Honestly, I think the flagship green team card is ur best bet because of that 24GB buffer. I mean, someone told me those AI tools really eat up VRAM, so the extra headroom is a lifesaver. It is pricey, but it saves three hours on long exports... worth it for heavy grading.

100% agree
