Thank You both very much. Rather than change from my i7/870, I ordered a replacement MB. (Gigabyte).
... Intel I7/870 that is a LGA 1155.
For what it's worth, the i7 870 is socket 1156. Intel is about to release a new socket that is 1155, which the socket 1156 CPUs won't fit in either.
I am sure that there is good reason for that but it just does not look like it from here. Oh well. It serves as a good reminder to double check the CPU/MB combination and make sure the socket specs are the same. Thanks to All who responded. I do appreciate it.
