Macpro 10.10 lag

I downloaded this app, and originally it says i used up to 3.2 GB memory without any program running and i only have about 200 MB left, but i kept on cleaning mutiple times (about 8 time) and now it has 2.44 GB avaliable. This is good, but also odd for me since I don't understand how can I be using 3.2 GB without any program running, and how can it clean up that much memory. Is the any setting problems that i should be aware of? Thanks

sorry about posting at wrong section, this is actually the first time i post a forum, I will be more accurate next time

sorry but what is Etrecheck? and how do i run that ?😕

UPDATE. I tried running the game with "Memory Clean" running. And when i open the game I have about 1.2 GB avaliable; but as game process, the memory left became less and less eventually hit about 20 MB left (starts to lag a lot when less 300 MB was avaliable), it was mostly File Cache and App Memory; then I used "Memory Clean" and the memory left would raise back to about 900MB but it still lags a lot. Any thoughts or solutions? 😟

Thanks

Btw, File Cache could sometimes be using about 2 GB memory and after clean it would become about 800 MB. and reguarding SSD and RAM, and really don't know what is considered good. I brought this computer in 2011 and used it only for school work and some games. And what is file cache anyways?

I downloaded AdwareMedic and removed Genieo, but what does this virus do? does it take up memory?

i checked the website, there are 8 GB, 12 GB and 16 GB etc.. but which one should I get? there's so many choices for same memory size.. also does SSD is needed? because my computer is pretty fast as long as I don't play game..
