I think it's easy to mine now. Better now than later.
Mine today, yesterday and tomorrow. I always have my ~3MH/S rigs running. Nothing worse than waking up in the morning and finding out one of my rigs hung itself overnight.
May I ask what cards you are using? I decided to buy R9 280x, but I'm considering the 270x instead.
As far as I know 280x performance is much better than 270x performance. 280x has currently very good price/performance ratio.
