Thanks...is there any performance difference between them...
and im assuming i can use either one in this motherboard right???
They are the same, so no performance difference. Any LGA1155 OR Socket 1155 processor will fit, it is just the vendors playing with words. It refers to the same socket, and the processors that go into XXXXX 1155 all will work. Be careful NOT to buy a Core i3/5/7 on the slightly different, but one generation older 1156 socket (LGA1156). Those won't work.
