What LLM hardware should I buy for my business?

With a $7k limit, ideally spending less / closer to $3k, what should a buy for my business?

I need to do considerable website scraping, data extraction from documents, and content generation. Most of this can be done in the background, and isn't live / customer facing, so it seems like the cloud is unnecessary. I'm now looking into buying some hardware. The workload is probably close to endless.

1. I was considering buying a mac studio when the new M4 refresh comes out with maxed out RAM.

2. I know the new 5090's are coming out, and I could camp out with my son and grab 2 of them if that was expected to be a good option.

3. I know Nvidia is coming out with it's own hardware similar to a mac studio to run LLMs. Should I be looking at that?

I care about quality. I can build a machine, or multiple of that makes sense.
