What is the cheapest graphics card I can get that will actually run Stable Diffusion without crashing my computer? Sorry if this is a super dumb question but Im really lost. Ive been watching videos and everyone says you need a ton of VRAM but I dont have a huge budget. Im in the UK and really want to keep it under 300 quid if possible. I just want to make some cool art for my dnd campaign and maybe some profile pics, nothing professional or crazy. Should I be looking for used cards or just grab something new? Any advice for a total beginner would be awesome because I have no idea where to start.

Honestly, skip anything new at that price point. Over the years I've found that VRAM is everything for stable diffusion. You should hunt for a used NVIDIA GeForce RTX 3060 12GB GDDR6.
- 12GB of VRAM is the bare minimum for decent generation speeds.
- Avoid 8GB cards if you can, theyll cause memory errors constantly. Grab a used 3060 and you'll be set for your campaign art.

> I started out trying to generate assets for my own campaigns on a card with only 8GB, and honestly, it was a nightmare. @Reply #2 - good point! Honestly, struggling with 8GB is just the worst. If you are really stuck on that 300 quid budget, you absolutely have to look at the second-hand market. Check eBay or local listings for an NVIDIA GeForce RTX 3060 12GB GDDR6. It is basically the king of budget AI generation right now because of that 12GB VRAM buffer. Dont bother with any of the newer low-end cards like the NVIDIA GeForce RTX 4060 8GB GDDR6 because you will just hit a wall immediately. Stick with the 12GB card and you will be making those D&D portraits in no time! Its gonna change your life, total game changer for campaigns.

Like someone mentioned, VRAM really is the bottleneck for this stuff. I started out trying to generate assets for my own campaigns on a card with only 8GB, and honestly, it was a nightmare. Every time I tried to use high-res fix or some specific models, I was getting constant out of memory errors. It basically kills the creative flow when you spend more time troubleshooting crashes than actually prompting. If you cant find a decent deal on that 12GB card, you might want to look at the NVIDIA GeForce RTX 4060 Ti 16GB GDDR6. Its definitely pushing your budget, but the extra VRAM gives you so much more breathing room for newer models like SDXL. If that feels too steep, look into the used market for a NVIDIA GeForce RTX 3090 24GB GDDR6X. You can sometimes find them for a steal if you catch someone upgrading to the 40 series. Having that 24GB buffer changed everything for me, I stopped worrying about optimization and just started making stuff. Whatever you do, dont even look at AMD cards for this. The software stack for NVIDIA is just way more stable and easier to set up for beginners. Its basically plug and play compared to the headache of getting things running on other hardware.
