Well, if you plan on overclocking and you feel confident in your components to overclock without an unlocked multiplier then the 1055T is a great deal, and is very overclockable.
However take note that only a couple games actually benefit from more than 4 cores, and even then the gain isn't too significant, usually. So they may not help too much today but they may in the future. And 50% more cores for 30% more cost is quite a bargain IMO.
