NVIDIA GeForce RTX 3070 Ti
$300$599 MSRP
The RTX 3070 Ti is a solid used gaming card with GDDR6X memory for extra bandwidth. However, at only 8GB VRAM, it's severely limited for AI — barely enough for 7B models at Q4. For the same used price, the RTX 3060 12GB offers more VRAM (which matters more for AI than raw speed). Best for pure gaming on a budget.
Best ForBudget used gaming — faster than 3060 but less VRAM
VerdictGood used gaming card, but 8GB is not enough for AI in 2026.
