The term "3D video card" is obsolete. Here's the evolution:
In the 1990s, "3D video cards" (like 3dfx Voodoo) were separate add-in cards only for 3D acceleration, paired with a 2D card for desktop display.
Every modern GPU (Graphics Processing Unit) handles 3D natively. The term "video card" or "graphics card" implies 3D capability by default.
Don't look for a "3D video card"—look for a modern graphics card matching your performance needs and budget.
