hiiii..
i m a small wisp…i m all set to setup a strong wireless ptp link frm my bandwitdh provider…i hav 70 coustomer connected evry time out of which more then 30 users keep downloading movies …all of time my three secotorial( attach to mikrotik rb 333 and 3 R52 card) are on havy dta traffic..so i need a real strong ptp link to feed my 70 coustomers..any suggestions..
Simple: dual nstreme or 2x dual nstreme bonded. Good luck! 
It depends on what speeds you are looking at. You could easily do a 40mbps link with standard ptp link over 5km without using high powered radios.

Well first I’d look at limiting my ‘users’ on the downloading of movies… They are using PtP (peer - to - peer) to get that stuff so limiting them on how fast they can download it will help you a lot.
Second - maximize bandwidth. While I will agree that Nstreme dual may be a little faster - can’t verify that and I have a couple running that right now… I favor two seperate Nstreme radios, then I use EoIP and Bond the two radios. I use the ‘balance rr’ method and arp monitoring of the links. Why this method - well if one the links fails and the other is still up then connectivity is not affected (connectivity not bandwidth). The available bandwidth is affected only if the client needs to draw more bandwidth than a single link can handle - otherwise the client will be unaware that one link has failed. Nstreme and bonding (I only use this in Point to Point links) seem to provide me with the best of both worlds when it comes to maximum bandwidth and failover capability. My opinion.
5km distance - well the MT r52 card would be a good choice of radio. The RB333 - though still in beta - is a great choice for this. I’d get two RB333 and four R52, four antennas - (I get the wideband 5.1 to 5.8Ghz antennas - easier to switch bands). Using the 5Ghz band also gets you out of the overcrowded 2.4Ghz band.
Hope this helps.
