You're missing the point. I'm not trying to argue about which system is better, I'm just saying that the comment I'm replying to is saying incorrect things about GPU performance. I'll answer your question anyway though:
You could build a complete desktop system including a GPU that's more powerful than the one in the M1 for ~$1000, but certainly not a 3080. They're very expensive, and nobody has any in stock anyway.
An RX 580 or 1660 would probably be the right GPU with that budget. (Although you could go with something more powerful and skimp out on CPU and ram if you only cared about gaming performance).
- a 3080 costs > $750 . Good luck buying one, I would if it wasn't out of stock. On the other hand the gtx 1050 mobile that is on the M1 can be easily found on eBay for < $50
- yes, you totally can. The best thing is that with a 1k.entry level you can start working on real-life projects that have deadlines and start earning money that will let you upgrade your gear to the level you actually need, without having to buy an entire new machine. The old components can serve as spare parts or to build a second node. You don't waste a single penny on things you don't need.
Even though, it's true, you can't brag with friends that it absorbs only 20 watts full load and the heat of the aluminium body is actually pleasant
