I game on Telkom (MTN Roaming) just fine, very stable with the occasional fluctuation or crap. It's not bad, and its not great. I'd not really advise it, but if you REALLY have to then go with a decent backbone provider, been gaming etc on 3G/HSDPA for almost 4 years and only really had about 50 hours max ? of total issues. Moving over to Fibre though because its a heck of a lot cheaper, 30GB of 3G Data this month cost me R1400! Expensive, when 20Mbit/120GB+1000GB(Midnight-6AM) with WA (+Free fibre Install + Router) for only R788/mo. Axxess even offers the naked Fibre lines, and then you can sign up with someone else for Data, although you do need routers etc, but to be honest, having the fibre pulled and spliced is the biggest task if you do consider it, ADSL is too much of a pain. Good luck man.
