I did want a M2 max studio, ended up with a 12 core Zen 4 + radeon 7800 XT for about half the money.

A Nvidia Project Digit/GB10 for $3k with 128GB ram does sound tempting. Especially since it's very likely to have standard NVMe storage that I can expand or replace as needed, unlike the Apple solution. Decent linux support is welcome as well.

Here's hoping, if not I can fall back to a 128GB ram AMD Strix Halo/395 AI Max plus. CPU perf should be in the same ballpark, but not likely to come anywhere close on GPU performance, but still likely to have decent tokens/sec for casual home tinkering.
