8360 works (see AXm77's screenshot above, he has a single one in the board with 3x slower cpus!)

there is a 300mhz per core clock bump (so cumulative over 16 cores that is a 4.8ghz increase) between 8354 and 8360.. not sure if the 30w per processor bump is worth it.. you're effectively adding a 120w 2.4ghz dual core or similar.. yes I know it doesn't work like that, but it's easier to quantify!
