I'm curious, how many times have you seen the motherboard or controller go? From the presentation it seems you have seen it often. Over the last 7 years or so, using configurations (scale for the time) like those above (although usually a little higher end Asus motherboard) I have not seen one fail in at least 15 systems like that. Many running 24x7.
I have seen lower end machines have issues (notably dell's) involving the motherboard and such however.
While definitely not a sample such as those in corporate environments (but we are talking about different hardware there), I just haven't seen the failure rate. And in the above case, you can have a spare motherboard for $100.
For another $200 you can of course buy the other card, and get better performance, which I don't dispute at all, but I think it comes into a preference question as to how it will be setup (and the costs associated with that). Some people are looking to control cost. In that case, and noting the issues with larger upgrades if the motherboard went, I would be inclined to just replace the motherboard.
Given this consideration, do you disagree? For a higher end, and performance driven installation, there are different parameters.

On bandwidth, if you can be wired, go gigabit...
