Depends on multiple factors. I have a pretty old 4-core 2.2GHz AMD machine. I used to have 1/8 rendering speed in relation to duration of original video (8 minutes to render 1 minute of original video). Then I bought a half-decent Nvidia card with CUDA and upgraded software, which utilizes GPU. Now I nave 1/6 rendering speed, so it is an improvement. Right, for 15 minutes of video my computer will need 1.5-2 hours of rendering.
Point is, if your software uses GPU for rendering you can keep the old computer, just upgrade the graphics card.
