3000 series and above are recommended for best performance. More VRAM is always preferable.

<summary>Why you should avoid older generations if you can.</summary>
<br>
Older generations of cards will work however performance might be worse than expected because they don't support certain operations.
Here is a quick summary of what is supported on each generation:
* 40 series (ada): fp16, bf16, fp8
* 30 series (ampere): fp16, bf16
* 20 series (turing): fp16
* 10 series (pascal) and below: only slow full precision fp32.
Models are inferenced in fp16 or bf16 for best quality depending on the model with the option for fp8 on some models for less memory/more speed at lower quality.
Note that this table doesn't mean that it's completely unsupported to use fp16 on 10 series for example it just means it's going to be slower because the GPU can't handle it natively.
Don't be tempted by the cheap pascal workstation cards with lots of vram, your performance will be bad.
