Honestly, those benchmarks can be pretty misleading because they usually test clean timelines without many effects. You really need to be careful with that 12GB VRAM limit on the base 4070 Ti. For 4K 10-bit wedding footage, especially if you're using heavy noise reduction or long multicam sequences, you're gonna hit a wall eventually. I would suggest making the jump to the NVIDIA GeForce RTX 4070 Ti Super 16GB GDDR6X instead. That extra 4GB of VRAM is basically your safety net against those random out-of-memory crashes Premiere is famous for. One thing to watch out for is render failure at 90% because you ran out of memory, which happens way more than people admit on the 12GB cards. If you check around at US retailers, you can usually find something like the ASUS TUF Gaming GeForce RTX 4070 Ti Super 16GB or even the ZOTAC Gaming GeForce RTX 4070 Ti Super Trinity Black Edition 16GB right around that $800 mark. Make sure you avoid the older 30-series cards now since the dual encoders on the 40-series Ti Super are actually useful for speeding up those long wedding exports. Just be careful with your power supply too, these things can spike a bit when you're pushing a heavy project. Honestly, skip the 12GB cards if you want to stay sane through this project... it just isnt worth the headache.
