I'm not sure Intel has great drivers or compatibility for AI, it might be sort of janky and limiting. Even with an AMD card I've struggled a lot, there are still plenty of things that only support Nvidia, full stop.

Edit to add: If you're willing to consider this option, you might also be interested in say, an Nvidia P40 or similar card. P40s have 24GB VRAM and you can pick them up cheap as can be, like $100-$200 price range. You need to 3d print or buy a fan cooler bracket for them. They are janky and limiting in a different way, they are old datacenter-style cards, they don't have fans or do video at all, they are a bit slow at AI tasks and only run on specific Nvidia drivers. But having plenty of VRAM for that low of a price is nice, and you can tune them down to about 125W so you can run a few of them if you can find enough slots or risers for them. AI usage does NOT require PCI-E X16 bandwidth, in my experience 4X is plenty and even 1X is probably okay with some penalty.

Edit again: Ah it looks like I guess P40s have doubled in price now too, the VRAM scavengers finally got to them. Still, if you were willing to go up to 1k price point, it's still viable.
