What do the Specs Indicate?

May 4, 2021
I'm looking to get my 14 year old son his first gaming desktop without breaking my bank. I know very little about the specs of gaming PCs so I'm wondering if you can explain the difference between the following under $750 gaming PCs? Does one stand out as better than the other three?

I asked him what games he currently plans on playing and he mentioned Fortnite, Apex Legends, and recording videos of him gaming.

- iBuyPower Slate MRi

- HP Pavilion Ryzen 5

- iBuyPower Mini 9300

- iBuyPower WA108AV2

Thank you for your help!!!
