Take a look at the detailed comparison I gave of two CPUs I'm looking
at, one an i7, the other a Xeon E3. Only $30 separates the two, but
the two CPUs also look very similar spec-wise. It's tough trying to
see what the Xeon does better that I'll actually take advantage of in
exchange for losing some clock speed vs the i7.

Generally speaking I'd say you are correct. However in this case the
max RAM supported is just 32GB either way. IO & Bandwidth look very
similar as well at least with the CPU specs. I haven't checked ECC
capabilities so that could be one slight advantage. And as to 24x7,
well, my current "server" is an old HP/Compaq dc5000 with a P4 CPU.
It's been running 24x7 for many years though I've replaced the CPU when
I discovered the L2 cache had failed. My i7-based desktop is nearly 4
years old now and also runs 24x7. I've lost one processor in it as
well, but I'm pretty sure that was a result of a power supply fan
failure I experienced earlier this year.

That's my biggest concern. If I go a true workstation/entry-level
server board and Xeon CPU, even if it's the E3, I'm guessing I'll run a
lesser risk of issues with ESXi than with a desktop board and the i7.
Of course if I go with an actual used server there's even less risk as
I can at that point check VMware hardware compatibility list. Still,
for the combined cost savings I get with both CPU & motherboard, I'm
still tempted to try the i7 route.

BTW, here are the specs on the two CPus. You can see they are honestly
very similar to each other.

Intel Xeon E3-1245V2

Intel Core i7-3770K

If I could afford a decent Xeon E5 then there'd be no question I'd just
go that route. But since a decent E5 is over $400 alone (thinking the
2620) that's not gonna happen. Almost seems like, then, it's a flip of
the coin going with an i7 or an E3.
