I have a normal HP 2000 Laptop with 4GB Ram (3.6GB Usable), 175GB free on my hard drive, and barely no programs on my computer. I have Adobe After Effects CS6 with a lot of plug-ins from VC, Red Giant, etc, and it seems to be running really slow. Especially when I use Element 3D or any plug in, it takes forever to render and even the final result is laggy and unprofessional. I was thinking that maybe upgrading my Ram to 8GB? Is there anything I can do to speed up AE and PR? I did the in menu options to change my multi-processing and memory and such, But I want to know what I need to do in order to make AE and PR run fast. Thanks!

With only 4GB of RAM, you should not be touching the Memory & Multiprocessing preferences for Render Multiple Frames Simultaneously multiprocessing; that is for computers with much more RAM.
You say that your output is "laggy and unprofessional". With a vague description like that, I can only guess, but it seems that you need to read this:
