I have an Intel Core2Duo e7400 processor, 3 GB ram, 120G SSD hard drive, and an nVidia Geforce 750Ti 2GB graphics card. When i gpu render vast scenes of about 100MB using Cycles in Blender, I receive the CUDA out of memory error. My motherboard maximum ram support is only 4gb DDR2.
So i wants to ask if I should buy an AMD RX480 8GB graphics card, or alternatively an i7 6700k processor with 16GB RAM to work with my 750Ti graphics card. Which one will be better for rendering large images and animations?
