I've never seen a single indication that the CPU itself is actually more
reliable. In your comparison, the main advantages of the Xeon are:
- multi-socket support (which you're not profiting from in a single socket
- ECC support (which means that a Xeon will be more reliable *if and only
if* it's paired with ECC memory). Also worth noting is that:
* some i7 models do have ECC support
* ECC memory typically has slower timings, though that may or may not
impact real-life performance for any particular application. For a lot of
applications, the impact is very small
- bigger cache; on paper, that's good for performance for some
applications, but for the specific purpose of trajectory analysis, it is
quite likely you'll swamp the cache no matter how big it is, so then I
wouldn't expect it to make much difference (though you'll never know for
sure without benchmarking)

Unless one buys a top-of-the-line i7 with very high TDP, running 24/7
shouldn't be an issue.
