Apex Legends not running, is buying more 16gb RAM and an SSD worthy for FPS - Helios 300 Predator

deeplix

So, I have a Helios 300 Predator GTX1660ti 16gb RAM and 126 SSD and 1TB HD. I have windows on my SSD so I can't put apex on it, so I have installed on HD. I feel like Apex is not running smoothly like when I was playing on the desktop, I have like 50-90 FPS while gaming and I feel like it is kinda lagging through the game when I get into a fight and there are shots everywhere. I already set it all on LOW, so my question is: is it worth to buy more 16gb and a 500GB SSD to put games on it? Will it increase the notebook performance? I'm asking because there is a sale running in a site and there are RAMS and SSD for very good prices.

Thanks in advance.
