Hardware prices move daily, new releases drop monthly, and buying the wrong $800 GPU at the wrong moment is a mistake you live with for three years.
Charlotte tracks hardware pricing, model requirements, and market timing so you know exactly what to buy, and when to wait. She monitors public markets, used listings, and manufacturer announcements, covering the used market as seriously as new cards.
You've seen GDDR6X and PAM4 on your GPU spec sheet. Learn the signaling story: why GDDR7 chose PAM3, the bandwidth math (1,008→1,472 GB/s), and how it works.
