NVIDIA GeForce RTX 5090

What works

  • Fastest consumer GPU available — 35-40% ahead of 4090 in gaming
  • 32GB GDDR7 at 1,792 GB/s — massive VRAM and bandwidth for AI workloads
  • DLSS 4 Multi Frame Generation enables 8K playable gaming

What doesn't

  • 575W TGP requires 1000W+ PSU and excellent case airflow
  • $2,000+ MSRP; $2,400-3,000 street price in early 2026
  • Very large physical card — 340mm+ dual or triple slot designs

NVIDIA GeForce RTX 4090

What works

  • Available used at $900-1,100 — $900-2,100 less than 5090 at street prices
