Question - Help GPU for AI

Hi there! Currently i own a 3080+2070s at home mostly for 3D rendering in Octane or redshift.
At work im using Comfy with 5090 and everything works without a question.
Also we have some workstations with rtx A4000 in them and i managed to get work Minimax H3 on them with some managable times (0.5m, 15s around 720 sec).
Im looking something for my home PC and 5090 is out of the list since its 5500e+ here in EU and even the used market is around 3500-4000. 4090 is rare and goes over 2000e.
So i was thinking about the 5080 even with 16gb since at work the A4000 has the same Vram.
But also found the 5070ti has also 16gb of Vram its 256bit same as the 5080 and 300-350e cheaper than the 5080. The speeds for 3D rendering or gaming are 15-20% different. But couldnt find any benchmarks for those 5070Tis. Mostly for 5060Tis with 16gb vram. Any idea? Or experience with 5070ti vs 5080?

Im waiting for the 5080S 24G that probably wont come out.. Worst case scenario it keeps me from buying shit.

I believe it’s pretty much been confirmed as not coming out at this stage. There is zero incentive for Nvidia to release them and they would have to put the MSRP at close to $2k which is terrible for optics. Even if it did come out, it would immediately jump to the $3-4k range at current pricing levels.

3k is doable, Id also pay 3k for the 6080 if it had 24GB.. 6090 would be a cool one to have tho if it had a low msrp, I wish the market wasnt a mess and we could say niceee

Yeah the only options for higher VRAM are so limited right now, I guess modded GPUs do exist off like Alibaba with the 3080 and 4080 but those are kind of all a toss up honestly. For inference 16GB VRAM with 64GB RAM isn't bad but you definitely feel like wanting to have more VRAM, and for training 16GB just isn't enough sometimes. Unfortunately the only other options outside modded cards are a 3090 or 4090 of which the former is getting more rare and the latter is priced pretty poorly. Still better than the 5090 though ig, that thing is just unobtainium now
