The xeon x3480 supports lga1156 sockets, just like the core i3-540 and also core i7-880 (also in consideration). But the i7-880 price around twice or more than the xeon x3480 while both have the same architecture and most of the specifications. Thus I'm considering xeon x3480. As per Intel's official website, h55 chipset is not listed as compatible with xeon x3480, but I saw people using the same processor in h55 motherboards from gigabyte. I'm not sure if I can do the same, and there I need expert suggestion.
