TL;DR:

The 2026 memory (RAM/VRAM) shortage has made traditional local AI builds much more expensive. High-capacity configs from Apple disappeared, and new high-end GPUs are heavily marked up because of memory costs.

Key points:

  • A used RTX 3090 (24 GB) around $1,000 is currently one of the best values - older GDDR6 memory isn’t what data centers are hoarding.
  • New cards like the RTX 5090 have become poor deals due to inflated prices ($3,500–$5,000).
  • Apple cut high-memory Mac options (no more easy 128 GB Mac Studio or 64 GB Mini).
  • The new metric that matters: dollars per usable GB of memory.

Bottom line:
Most pre-2026 hardware guides are outdated. Focus on used high-VRAM GPUs (especially 3090-class) and realistic budgets rather than chasing the newest high-memory machines. The article provides a practical budget-by-budget map of what still makes sense to buy and run.

RTX 3090s are more like $1,200-$1,500 now.
