You don't need to use Add2PSU. You have to either short 2 pins from the 20/24 pins connector (or use some custom designed connector) so that if you turn the PSU switch to on, it does turn on. You just have to make sure that the PSUs that are not linked to the motherboard are switch to on first (before turning on the computer). I use the round part of a paper clip to short my PSUs and put electrical tape over it. It's been working like that for 2 years without problems.
I am running 3 x 6970 from MSI and they are fine so I would not hesitate to pick the 7970 from them. Go cheap and buy more of them.
