NVIDIA GeForce RTX 3070
$250$499 MSRP
The RTX 3070 was the 1440p champion of its generation and remains a capable used gaming card at around $250. The 8GB VRAM is its biggest limitation in 2026 — fine for gaming but too small for meaningful AI work. Lower power draw than the Ti variant makes it easier to drop into older builds.
Best ForBudget used 1440p gaming
VerdictGreat used gaming value at $250, but skip it if AI is in your plans.
