Well the decision really depends on what you are needing this for. The W3565 will clearly be faster if it goes head to head on single threaded apps but it also carries a higher tdp of a 130 watts compared to 80watts with the E5520. If whatever you are using this for can take advantage of 16 threads then the dual setup will be faster. Also I noticed for the W3565 it only supports up to 24GB where as the E5520 will accept up to 144GBs per processor. Both support DDR3 up to 1066 and both have 8MB of cache the only clear difference is the core clocks W3565 wears a 3.2ghz clock and a tad faster QPI of 4.8GT/s. So like i said if whatever you will be useing this setup for cant take advantage of all of the 16threads of the dual setup then the W3565 is the winner.
For your motherboard you will have to be a little more specific about what you will be needing this for to choose a motherboard for it.
