Default South Bridge Bottlenecks

So as far as I understand, a typical South Bridge has a bottleneck of 4000 MB/s.

I was thinking that rather than have lots of RAM (I do sample libraries) I could use 3 Samsung 960s, which have 3500 MB/s read, however 2 of them reading at once will already saturate the SouthBridge, so... maybe I'll just get 1 plus a regular SSD.

However... is 4000 MB/s too slow? I mean, if I'm running an orchestral VSTi template [I know I'll get refered to VI control, but I feel Reaper folk have better hardware knowledge, and are more willing to think outside the box. Also I just like you ] with 50 or 100 VSTi... normally I'd need 64gb of ram...

But do I need to match RAM speed? If I have minimal RAM buffers (32gb of RAM), plus fast SSD read times (4000 MB/s) can I get away with it? Or do I really need 64gb (or 128 gb as many pro composers are using).
