What Mizzou said.
I just replaced the 1055T with a 1100T while I wait...and wait...and wait for the !#&*%!#@ Bulldozer to come out...but I digress, I thought I might be able to get a bit more OC out of it as it's binned at the top of the series. I did get an extra 150Mhz from it and at a bit less voltage, but that is never guaranteed, so you have to decide if the extra 30 euros is worth it to you.
