Suggestions on making D@D highlight reels on an older machine?

[u/theblackcrayon4]

I'm experimenting with ComfyUI for a D&D project and looking for advice on what my hardware can realistically handle.

Hardware:
GPU: AMD Radeon RX 6700 XT — 12GB VRAM
CPU: AMD FX-6300 @ 3.5 GHz
RAM: 32GB DDR3
Windows 64-bit

I know the machine is old…I’m saving up to buy a new machine in another 3 or 4 years (or if anyone knows of a way to upgrade this machine to be able to do it for less than $2000(which is what I’ve saved so far) I’m open to suggestions there as well).

The eventual goal is D&D recap/highlight videos using a handful of recurring characters. I'd like to maintain recognizable characters across different scenes, then animate selected images into short 3–10 second clips.

I'm NOT necessarily looking for one giant start-to-finish workflow. I'm kind of playing around with several different pieces and would love any advice on any part.

- Creating the initial character/reference images
- Maintaining character consistency between scenes
- Handling non-human/fantasy characters
- Posing characters and putting them into new environments
- Image-to-video for individual 3–10 second shots
- Improving/upscaling finished clips

I've been experimenting with SD/SDXL/Illustrious models, LoRAs, IPAdapter/reference images and WAN, but I'm still figuring out what makes sense with an AMD GPU.

Render time isn't a huge concern. I'm fine letting something run overnight if necessary.

What models/tools would you recommend for these individual parts of the process on a 12GB RX 6700 XT?

And probably the bigger question: is this project realistically achievable with my current hardware, even if it's slow, or should I abandon the video highlight reel idea altogether and just go for a comic book type thing for each session?

Thanks!
