Need Advice: Is Now the Right Time to Invest in an AI Computer?

Hey everyone,

I’ve been researching AI computers lately, and I’m torn about whether to upgrade my current setup. With all the new hardware featuring NPUs and AI-accelerated chips, it feels like we’re at the edge of a major shift in personal computing. But I’m not sure if the technology is mature enough yet or if I should wait. Here’s where I’m stuck:

My Situation:
I’m a developer working mostly with machine learning models (mostly computer vision and some NLP). Right now, I’m using a gaming laptop with an RTX 3070, which handles my workloads okay, but I’m hitting limits with larger models.

My Question:

Hardware Trade-offs: For local AI work, is it better to stick with a high-end GPU (like an RTX 4090) or jump to a system with a dedicated NPU?

Thanks in advance for the help. This feels like a big decision, and I’d hate to jump in blindly.
