Windows generally works but there may be a somewhat small performance hit. IMO linux is much easier to get to work judging by all the github issue threads I see able SD/LLaMa stuff on windows - but I don't use windows so I dont have personal experience.
4090 24GB is 1800USD, The Ada A6000 48GB is like 8000USD and idk where you buy it? So if you want to run games and models locally the 4090 is honestly the best option.
EDIT: I forgot - there is a rumored 4090ti with 48gb of vram, no idea if thats worth waiting for.
The A6000 is actually the old generation, Ampere. The new Ada generation one is called 6000. Seems many places still sell A6000 (Ampere) for the same price as RTX 6000 (Ada) though, even though the new one is twice as fast.
Seems you can get used RTX A6000s for around $3000 on ebay.
You're kidding? So they called it the RTX 6000, then called it the RTX A6000 for ampere, then back to RTX 6000 for Ada?
Why do they do this? Sometimes consumer products are versioned weirdly to mislead customers (like intel cpus) - but these wouldn't even make sense to do that with as they're enterprise cards?
Actually the first one is called Quadro RTX 6000, while the Ada one is just RTX 6000 without "Quadro" in front. Not that it makes the naming make much more sense.
According to GPT-4 the next generation one will be called Galactic Unicorn RTX 6000 :D
