I was able to get a bundle deal from Microcenter here in SoCal with the Ryzen 9950x, motherboard and 32GB of RAM for $699. They have since removed the RAM from all the bundles.

While thats a sweet upgrade for people with an older desktop that can support a motherboard swap, its worthwhile to point out the ram is probably insufficient.

RAM usage for a lot of workloads scales with core/thread count, and my general rule of thumb is that 1G/thread is not enough, and 2G/thread will mostly work, and 4G/thread is probably too much, but your disk cache will be happy. Also, the same applies to VMs, so if your hosting a VM and give it 16 threads, you probably want at least 16G for the VM. The 4G/thread then starts to look pretty reasonable.

Just building a lot of opensource projects with `make -j32` your going to be swapping if you only have 1G/thread. This rule then becomes super noticeable when your on a machine with 512G of ram, and 300+ threads, because your builds will OOM.

Ha, I was going to purchase a 96GB kit, but that's when I first noticed that RAM prices were getting crazy.
