What has significant effects on stable diffusion generation times? I'm trying to learn to build a pc for that specific purpose and because I'm starting from basically 0 its kinda hard. Obviously the GPU matters the most, but it also can connect to the motherboard through different gens of pci express. From what I know (I think?) this wouldn't affect generation much, only initial loading. RAM, I have no clue what effect it would have on anything, same with CPU. So how do these 2 affect stable diffusion?

Just get two 3090s with a cheap Xeon and call it a day.

>>105705498 (OP)
ram should only have a significant effect if you're offloading to it, same with cpu

>>105705529
So as long as the GPU is good enough, these 2 are borderline irrelevant?

>>105705538
You should have enough PCIe lanes for your GPUs

>>105705510
One 3090 is already almost my entire budget for this PC (in Poland a single used one costs like 880$).

>>105705542
From what I read almost all motherboards already have 16 lane slots, which would be enough for even a 5090.

Just use online services if you're poor.

Why would you run just a single one of them?

>>105705569
Because 1 is like my monthly wage atm. Also I thought running multiple cards isn't easy software side. Is it as easy as just plugging another card and running the program, or does it require more setup and only some things work with it?

>>105705607
It's that easy, unless your motherboard or platform starves the second GPU.

Good to know, thanks.
Also fuck, that's another variable to consider. I guess I'll look into the prices of double slot motherboards and see.
