(Complete Newbie) Need help knowing what to upgrade

[Benorage]

I need some help on knowing what to change with my laptop so it can run games better. As the title suggests, I know hardly anything about PC's so I'm not sure what I'm doing wrong hardware wise. I did try upgrading my laptops RAM a few years back from 8gb to 20gb but I didn't seem to change much so I gave up back then. But now I'm back and more determined to make ***** actually run on my laptop. Most Ps2 games run at around 60-70% speed making them essentially unplayable. I've messed around with the settings to see if that changes anything but I haven't really seen a difference. I'll post my specs below and would really appreciate any suggestions on what I need to change. Don't worry I'm not asking you to look for parts for me, that's my job, I just need to know what's pulling me down performance wise since I have hardly any knowledge about stuff like this. 
If there's anything crucial I forgot to post let me know, thanks in advance.

basically, you need to change the cpu.
so, the gpu too
So, the mobo too
