KFA2 EX Gamer GeForce RTX 4070

Built on the GeForce RTX 4070, this card brings 12GB of GDDR6X memory. Clocks run from 1920 up to 2550 boost, drawing 250W — a solid 650–750W unit suffices. At 323mm long it needs a full-size case; display outputs: HDMI 2.1, DisplayPort 2.1. 12GB of VRAM is the sweet spot for 1440p in current titles.
