95w does what it sounds like it does...uses less power
. Go for the 95.
Also based on the model number (MBOX vs IBOX at the end), it seems like the 95 is the c3 stepping, which means it'll overclock better. At that price, do you think you'd be able to go a little more and get this though?http://www.newegg.com/Product/Product.aspx?Item=N82E16819103808&cm_re=phenom_955-_-19-103-808-_-Product
the 955 has an unlocked multiplier making it easier to OC.
