routerBoard - which one? ...or routerOS?

Good evening,

I renewed the network in my society, we are 50/60 people.
We had 1 network (test servers and clients) with 2 gateways (2 internet connections), i decided to divide networks phisically, and put a mikrotik in the middle.

I installed routerOS over a virtual machine, vmware esxi, it has 4 Gigabit interfaces (2 trunks with firewall, 1 for Users lan and 1 for test servers). We use 100mbit internet connection.

It has really good troughput, but i don’t like too much to have a router over a virtual machine.. it add a big point of failure to the network..

so i’m going to buy a phisical mikotik router. Now CPU is 2,4GHz, 2MB Ram, over the virtual machine, but i don’t really understand how much CPU we are currently really using.. winbox says between 15% and 30%..

In this context, what routerBoard do you suggest?

Do i have to do 2400Mhz/3 -:- 2400Mhz/6 → 400-:-800Mhz? ..So if i take the 680Mhz version it will be always between 66% and 100%? would it be enough?

So.. what routerboard do you suggest?

Thanks for patience

Yo can check mirkrotik’s catalog, RB1200 seems to be one of the most robust routerboards

you can also this option RB1100AHx2 dual core!
