Thank you for contacting the Intel Communities.
Actually your reasearch is good.
Basically, the difference would be, no graphics from processor and ECC support (Motherboard has to support it as well).
The advantage of Intel® Xeon® over Intel® Core™ i7 would be data processing as you already know as well.
So if the board supports ECC and the processor desired to be used, you should be good to go.
If you require any further information or support, do not hesitate to contact us back.
