Unless Premiere's specs/requirements specifically say it supports Quadro for acceleration and/or it lists *only* Quadra (and not Geforce), then the Geforce is likely to be the best bang for the buck. The Quadro line is mainly distinguished by their CAD-and-pro-3D-oriented drivers that prioritize stability, high geometry counts, and accelerate line antialiasing and other functions. These days most acceleration for non-3D apps (and an increasing number of 3D apps) is handled by GPGPU libraries like CUDA and OpenCL, both of which are supported equally well on Geforce and Quadro devices.
