Dual 5GHz radios vs doubling bandwidth (40/80/160)

We're running a 40MHz 802.11ac deployment today and we're seeing quite a lot of throughput need (28 clients downloading 7 GB at the same time and that kinda stuff). Got me thinking about MU-MIMO, which isn't really useful as our clients doesn't support it, AND;

What would be the benefit of running two 5GHz radios vs just going for 80MHz bandwidth - if any? We're running Cisco 2802i APs, and I can't really see why dual 5GHz would be beneficial unless you're allready running 160MHz on your primary 5GHz radio?

Anyone running dual 5GHz who got some points to throw in?
