RME Multiface - PCI vrs PCI-E

I always feel a sudden urge to stab myself in the eye with a fork when I have to use it. I'm sure it's simple as hell when you get used to it, but every few months when I sit in front of it and try to route something, I get some sort of problems.

+1. I don't get it. To be true I don't even make ANY use of if I don't have to because of using outboard gear.
 
I have no use for that totalmix nonsense, but I LOVE this thing. I can crank the buffer all the way down to 32 and have like 2ms of latency! even with a bunch of plugins running. this thing is crazy, can't believe I waited this long to upgrade.
