Well, sorry ChipX, but I can't stand it when people say that it has an unlocked multiplier. I know it has an unlocked multiplier, but being a monster overclocker, I know it won't help overclocking because you will reach the same sealing with maxed out settings. That is the same with the memory because once the memory is maxed out, you can lower the multiplier and it will only decrease performance due to the decreasing clock speed.
For example, if my sealing is 3 GHz on a 200 MHz base, I can only do this...
15 x 200 = 3000
10 x 300 = 3000
12 x 250 = 3000
4 x 250 = 2000 (HTT)
3 x 300 = 1800 (HTT) (Boo! Limitations)
This is considering the memory holds up. I don't see a plus for the unlocked multiplier. However, I will say this. If AMD, would've enable 3 simultaneous HTT links (like the Opterons) with the FX only, and included unlocked multiplier, and 1MB L2 cache, that would've justified the $899 price tag on the FX-55. Other than that, I don't see an unlocked multiplier costing you 600+ to put in.
