yeah i think your comp is perfectly fine to handle an ssd and preform good. i would say defintely get the ssd or another good harddrive for a low price and put the os on there.
money is tight but a good harddrive mihg tjust be what you need. your computer is pretty new and can handle some complex stuff. rendering and editing might be a task depending on how heavy your effects are, because idk what typ eof graphics card it has. it says amd which is a good company, but i dont think its a gaming level card, so i might just be able to handle games with settings at medium to high at the very least.
also the ram you have will determine how slow your computer will get doing a bunch of task that involve memory, like rendering.
if you have at least 4gb of ram then you should be okay. though 8 would be preferrable for future use.
