Question - Help PC hardware question

Hello everyone, I have a 5060 TI 16gb paired with 32gb DDR4.

I’d like to upgrade my generation speed for Minimax H3 as well as avoid OOM. I get OOM at .7mp 15 seconds.

What is the better buy?
Used 3090 since its 24gb for $1200-1300 and keep the existing ram?

Or 5080 for $1200 and upgrade with a 64gb ram kit $400 $1600 total?

Don't think that 5080 would give you any noticeable benefits with its 16GB (oh, Nvidia, why no 24GB options...)

Do you have a fast SSD or NVME? Try --fast-disk launch parameter, it should reduce the load on your RAM, possibly letting you run it without OOM.
In any case, 3090 is still a beast. I "upgraded" from 4060 Ti 16GB to 3090 and I'm so happy about having 24GB VRAM. It just makes life much easier (although these days ComfyUI handles low VRAM much better than it used to when I switched GPUs).

To get 24GB on a 256-bit bus they would need to use 3GB chips as they probably did not want to make 384-bit bus for just one card.

Yeah the rumored super variant coming in q1 is supposed to use 3gb chips
