So I’ve gone to an SSD and I’m trying to get the most out of my CPU for recording, mixing etc. So, like the question says, will a new card with a GPU provide any significant boost and CPU performance by reducing its load? Thanks for any insight.

I haven't noticed any difference in system performance using the built in Intel on a Dell laptop that also has an NVIDA video option.  Maybe there is some that I don't see.  A separate video card can't hurt as long as the power supply can handle it (that is a consideration on Dell desktops as they generally only spec the power supply for what the PC needs and it likely does not have a power connector for a video card).  I do support on the Dell forum and often see power supply issues with add on hardware.
 
Post the Dell model (e.g Inspiron 530) and I'll check the spec's.   

Hey thanks. I’m using a Dell XPS 8500 i5 desktop from 2012.

I tested a nvidia GTX 950 on my DAW, and could see no improvement there, over the integrated Intel HD graphics.
 
However, I moved that GPU to my media center PC and now I can play games at full HD 1920 with max settings and no frame rate dropouts. 

Billy86,
As far as audio processing goes, I refer your question to the following article published in 2009 by SoundonSound.  Here is the link:

The short answer is yes.  As with any computing desire, you need to flip the correct switches or have a program that will do it for you.  Then there is the economics.
 

You have to think about the context in which you're using a high-end video card.
 
If you're playing a video game (looking for high 3D frame-rates), then absolutely a high-end video card will aid performance.
 
For DAW purposes, where we're not pushing graphics hard at all... a high-end video card will not increase performance.  You'll not be able to run additional plugins or work at lower audio latency.
 

• If you want to run four large displays, a higher-end video card will be necessary.
• If you do a significant amount of video editing/rendering, a higher-end video card is recommended (aids video processing/rendering).  Some video plugins (ie: New Blue Titler Pro) won't operate without a higher-end dedicated video card
