Select hardware for fast Windows-10 CUDA-based vision processing system

We want to put together a fast system for vision processing. We currently have a Intel Core i7-9700 CPU with a Nvidia Quadro P1000 which we use for both CUDA and OpenCL. We are using this for a custom vision system. We're looking for a hardware expert who can suggest Windows 10 system hardware that will give us roughly four times the image processing ability than what we have now. We need it to go about four times faster than it is now. The images we are using are 4096x3072, and the vision system uses a neural network which is processed using GPU: CUDA, with additional processing using OpenCL.
