Client station for 3x3 view

[TheF 0]

I have a powerful server machine specced for recording 40ch IP cameras and a separate powerful client station to view all 40ch IP cameras.

It's working fine, no problem at all.

 

But I would like to add one more client station (server says it can have several client stations), and I would hope to not spend as much money on the second client since it will only stream 9ch IP cameras (4megapixel, each of them).

 

Any recommandations to client station specifications?

Do I need an i7 processor, or can I make do with an i5?

Do I need 16GB RAM, or can I make do with 8GB?

The software allows for showing a substream of less than the original 4megapixel (especially since 9x4megapixels is way more than the monitor can show anyways).

 

Any suggestions?
