No, it won't. All the stuff you describe merely runs on the CPU. if you want it faster, you need a better main processor and more RAM.
As Mylenium said - more ram and better CPU. Tell us what CPU and RAM you have and maby there will be some room for improvement. And of course remember about optimizing your project - most of the times there is a problem - not in computer specs.
Hi, my CPU is a I7-3770k (no overclock for now), 32 GB RAM, SSD 950 PRO 256gb pci for the media files, SSD Sandisk Plus 240gb to cache and previews, Ssd Corsair Neutron Gtx 120gb for the OS.
Hmmm... your specs seems ok - similar to mine on one computer. So ... maby there is somethingwrong with optimalisation of your workflow.
1. That article should help: Improve performance in After Effects
2. If you are working with particular - check those videos:

3. If you are using lots of expressions - bake them/convert to keyframes.
4. Reduce resolution of source images. So if you are using imaes and you are not zooming/scaling them to much - keep them as close to your composition resoution as possible.
5. If you don't need higher bit depth - keep it on 8bpc
I agree man. The CPUs have evolved little in recent years, each new generation of processors, has only about 5% increase in performance, what is very little. The cause of this is that Intel has no more competition from the AMD as there a few years ago. There is no stimulus for producing great leaps of innovation. So I think silly to spend money to upgrade, even after three years. Maybe in 2018 I will do a upgrade in my motherboard and CPU. For now, upgrade seems something to boast and show to friends, enthusiast thing with money left over.
