The 1100T is a very impressive chip. It's fairly affordable, has a high stock clock speed, offers flexibility with that unlocked multiplier and consequently clocks well.
Because of the multi I don't think I'd need to specifically recommend a decent motherboard for heavy overclocking like with the 1055T. As long as your board was reasonable specified and supported chips up to 140w I'd imagine you'd still get a reasonable overclock from the 1100T.
Multithreaded performance was understandably top drawer with the 1100T turning in a very creditable performance across all the desktop style benchmarks.

As before I found that the gaming performance to be right up there with the competition. As games become more multithreaded I'm certain that those additional cores will help and although the majority of gaming situations currently favour clock over core count AMD have that covered too with their Turbo Core system pumping the 3.3GHz hex up to a 3.7GHz single, dual or tri core when needed.
Pros
+ Very impressive overclocking performance (some users reporting 4.4GHz - with sufficient cooling)
+ Smooth windows and gaming performance
+ Great multithreaded performance
+ Cool running at both stock speeds and overclocks
+ Still pretty well priced considering the unlocked multi and high stock speed
+ Great compatibility with both older AM2+ boards and future AM3+ boards too
Cons
- Absolute performance can't compete with current Intel hex cores and is similar to Intel quads

All in all the 1100T covers many of the bases most prospective purchasers are looking for. For users used to the AMD pricing scale it is a little bit of an investment but I personally think it would be a worthwhile one. Even without overclocking AMD's clever turbo core feature dynamically transforms the chip depending upon multithreaded load to provide optimum performance at all times. The overclocking potential and the cool running nature of the chip only goes further to cement its position as AMD's flagship CPU.
