Hello, I'm looking at these 2 cpu's, the AMD Phenom II X6 1055T Thuban & the AMD Phenom II X6 1090T Black Edition Thuban. Other then the GHz & $100.00 is there any other difference with these? I ordered the black edition last night on newegg & then they sent me a link for the 1055t today & I don't know if I should cancel the order & get the 1055t thuban. With the $ 100.00 between the 2, I could buy more memory or a better motherboard like the GIGABYTE GA-890FXA-UD7.
Thanks for your help on this.

The only other difference is the 1090t has an unlocked multiplier and the 1055t doesn't. That said, I still recommend the 1055t for overclocking.

I recommend the 1090t under the following circumstances:
-Will never overclock
-Very badly need the extra 0.4GHz
-Are gaming with multiple GPUs in crossfire or SLI, where 2.8GHz might not cut it.

Otherwise, the 1055t is capable of overclocking as well as the 1090t for overclockers.
It is still very capable at stock 2.8GHz for most other applications.
The $100 extra is not worth the upgrade to the 1090t for most people.

The difference is 0.4Ghz and an unlocked Multi.
If you plan to OC, then 1090T might be a better choice.

However, what do you plan to do with this? Gaming wise a 955 is enough.

3.2-2.8=0.4 :p 

And I agree with that. The 955 will be a better choice if you intend to purely game. It is also more than enough for most normal applications. But if you can use the extra 2 cores with your intended uses, the 1055t is worth it.
For example, if you run a lot of VMs like my friend does, it's very nice being able to dedicate 2 cores to one VM, two cores to another VM and still have 2 cores to play games. There's also encoding and video editing that most programs can use all 6 cores.

I know, edited when it came to me, for some reason I though the 1055T was 3.0Ghz.

I do not plan to overclock, I have never done it so far.I don't play many games but I do some editing & converting of movies with VSO ConvertXtoDVD I'm building a new machine & I don't plan on doing another for long time, I want to buy the better of the 2. It will be an all around machine. I'll go with the 1055t.
Thanks for all your help on this, I appreciate it.

The Phenom II X6 1090T will 'turbo' up the cpu multiplier from 16x to 18x across three or less cores in lightly threaded apps while down-clocking three cores.

My understanding is the 1055T has a wee bit more boost of 500MHz in 'turbo'. That of course, would be from 14x to 16.5x

Of course, it would be interesting to see how 'turbo' used in conjunction with upping the clock let's say, from 200MHz to 240MHz, would boost 3 cores with the multiplier increase, but most folks disable turbo when they OC.

Asus has a feature (I have not had the pleasure) which expands the multiplier turbo somewhat (which would certainly apply to the unlocked 1090T). In an early BIOS version on a M4A785TD -V I built for someone with the 1055T a few months ago --- I played with it for an hour or so and the boost was most certainly more than 500MHz when I upped the clock.

I didn't want to press my luck - or the CPU/mobo - however. If you get the clock up in the 280MHz range (which seems common on some mobos with the 1055T), you may be looking at a 700MHz or so boost.
