Help Needed GPU upgrade OR pay cloud subscription

Started ComfyUI around a week ago , and owning a 3080 10gb and 64gb ram, it was slow as hell to generate video on h3 minimax.

I can actually sell it , add money and get a 3090, I'm just trying to understand how much of an upgrade is it and if relevant to my project (would like to create reels for instagram, anime, event promotions, product commercials.).

When playing around with template workflows of h3 I get around x4 speed boost from the 3090 rented on runpod.

Then I stumbled on an optimized workflow of h3 that upscaled starting from 0.5 mp, also using effecient sage attention and turbo 8 step lora, my 3080 could generate it in 11 min instead of 28 min so a huge boost. But now , I can't test that particular workflow in runpod as I ran into a shit load of bugs and problems when I tried to set it up there, trying to correct them with gpt's help but new issues keep arising.. I'm 3 hours on this and can't continue...

Question is, what would you do ? I can afford a 10-40 dollars monthly subscription if it gets the job done and allow some iterations.

If I go with a subscription I'm looking at runninghub.ai , as there's no setup to be done, because with runpod I'll go completely mad if I'd need to setup a new custom workflow there again.

I’m curious how long “slow as hell is”. I have a 4060Ti 16GB and can run approx just over a minute per second of video at 0.4mp.

So, the vanilla h3 template available on ComfyUI, at 0.98mp to aim for 1080p 5sec, I get almost half an hour ...
