After randomly breaking the AM4 CPU and motherboard in my 4 year old PC last year and seeing that at the time I'd spent almost a new PC to get new parts and rebuild it. Less if I wanted to do a complete rebuild myself but I'm over building PCs. I've done that for years.

It was an expensive mistake as I bought a few options to experiment including a NUC and an M4 Mac Mini but eventually bought a 9800X3D 5070Ti PC for <$2 and for no reason in particular I bought a 64GB DDR5-6000 kit for $200 in August or so. I checked recently and that kit is pushing $1000. I also bought a 4080 laptop and bought a 64GB kit and an extra SSD for it too last year.

That's pretty lucky given what's happened since. I don't claim any kind of foresight about what would happen.

I do kind of want to take the parts I have and build another AM4 PC. The 5900XT is not a bad option with 16 cores for ~$300 but my DDR4 RAM is almost useless because the best deals now are for combos of CPU + motherboard + RAM at steep discounts.

You can get some good deals on prebuilts still. Not as good as 6+ months ago but still not bad. Costco has a 5080 PC for $2300. There's no way I'm going overboard and building a 128GB+ PC right now.

I've seen multiple RAM spikes. We had one at the height of the crypto hysteria IIRC but this is significantly worse and is also impacting SSDs. I kinda wish I'd bought 1-2 4TB+ SSDs last year but oh well.

We're really waiting for the AI bubble to pop. Part of me think sthat'll be in the next year but it could stay irrational substantially longer than that.
