Stuck between AMD 955, 960t, 970, 975, and 1055t

I realize that is a large list of CPU's to choose from, but I'll try and help with narrowing it down.

I really don't want anything for much more than $150. This will mainly be used for gaming and will be coupled with a 6850, or a 6870 if I can save money from the CPU. I do some video editing and converting, but not a lot. I do plan on doing more gameplay footage once I get my new build though. I will be getting a Hyper 212 EVO and definitely plan on doing some good overclocking. So I'm trying to figure out which CPU will give me the best performance after overclocking. The gaming part is definitely much more important than video editing.

I've heard some of these have good overhead for OC but others have a really low ceiling. Unlocking the extra cores on the 960t would be great, bt it isn't always a guarantee.

As of now, these are the prices on Newegg
955 - $125 but sold out for now
960t - $125
970 - $140
975 - $160
1055t - $150
