Summary
Unlike the GeForce which is targets toward consumers and gamers, Quadro is target toward graphics designers, therefore only seen on workstation PCs.
Unique to the Quadro GPU families are the ECC-enabled video memory and unlocked double-precision float point performance. OpenGL acceleration is greater than its GeForce counterpart.
Its rival being AMD's FirePro.
