GPU vs CPU upgrade, GPU preview / CPU bottleneck?
I'm currently using Adobe Illustrator CC, latest version, on a PC with a Nvidia Gforce GTX 1660 GPU and a AMD Ryzen 5 3600 6-core CPU.
I normally use GPU preview, but I use extremely large files with lots of objects, layers, embedded images and appearance effects. Because of this I often run into large amounts of lag.
I have already maximised my workflow efficiency such as using linked images where possible, and saving all high-intensity effects and rendering to the last stages of each project. I have now hit a wall where workflow efficiency is no longer helping and I am considering upgrading my CPU or GPU.
I'm considering getting a high-end GPU such as the RTX 3090, or perhaps a higher-end CPU, but my question is which will be a more effective upgrade in the first instance. Does GPU preview bypass a CPU bottleneck for rendering effects like blur and zooming? Or am I better off spreading my money out and getting a mid-range GPU and CPU upgrade together?
