Yes it is. Depending on your requirements even a smaller RB could do this.

Is it fast enough?

Well, it depends... What are your requirements?
If you just get a default route and/or some routes from a local IX, you will be fine. But if you get full tables from several Peers you won't get happy with it. The Problem is that BGP can "eat up" the whole CPU during convergence which leads to very high RTTs and even timeouts. In this Situation you should use a router with a multicore CPU like the CCR series or if you're on a Budget you could use the RB1100AHx2 or RB1100Hx2.

I have 3x of them on stock and I must use them.
I'll give him a try and hope that it will be enough for some time, until I buy something better.
I'll get full table from one peer and I'm talking about 100-150Mbps of traffic. Hope it will work,,,

I'm sure it works. We still use RB1000 without problem. It needs some time for BGP to come up and
you should avoid using snmp as it may give problems with the big routing table.
Be sure to do nothing else than BGP on this devices.

The 1100AH is perfectly fine for a BGP peering router. If you aren't going to have more than one link, then take a default and filter out the rest of the routes.
