Accidental - miswired PCIe power such that it went back into a SATA/molex modular port.

Somehow managed to not break anything else though, but an experience not to repeat.

Sounds like a Primus song but not quite.

No, the R9700 I have got fried by a power supply fault, and GPU replacements are not always trivial.

Of the two affordable options for good 32G compute, the R9700 would be the best of the two (compared to the Arc Pro B70).

Plenty - you could do both with an R9700.

Unless it's CUDA only, a fair amount of software now supports AMD ROCm. And if you're already wanting to write an inference engine, 32G will be more than fine.

I've had a R9700 and it'd run the lower quants (4-5 bit?) of Qwen 3.5 27B reasonably attached to Hermes Agent. Not quite a 3090, but still respectable speeds.

I wonder if this is from efforts to maintain the difference between upstream and Edge - such that Edge is trying to simplify development by following Chrome/Chromium closer.
