Actually, you're both wrong. Not directly, though. I assume RiotShielder misread it as you want to render 3D objects in games faster, which is on the GPU. All the CPU really does is to read code, so a better CPU would execute things faster and smoother. To work with rendering 3D objects in software such as, for example, Maya or Blender you'll need both decent GPU and CPU, but to render the finished product and same it onto your harddrive is processed by the RAM.
