I am planning to built a budget video editing system so I've wonder which Graphics card should I buy a new 1050 TI which costs $200 USD or a old but brand new R9 380 that costs $117 USD (From my friend ) which is cheaper but performs better in most games but I don`t know about the productivity side. I am going to use Premier Pro for Editing. Which is a better GPU for Editing in Premier Pro, Which is more optimized Opencl or Cuda. Which card should i buy ? Please Help...
