Which Opteron (165-180) will overclock the highest

[529th]

Which Opteron (165-180) will overclock the highest. I'm building a gaming machine. I mostly play DODS and other HL2 mods and possibly Red Orchestra. My current setup, when the server gets full, gets <40fps on average.

So far here's what i picked up:

Lian Li PC-V1100b Silent Plus
Liberty Enermax 620 PSU
WD Raptor 1500ADFD
Creative X-Fi Elite Pro (worst price for performance, but i was stuck in the scenario)

Here's the rest of what im thinking:
Opteron 939 dual core - highest overclocker between the 165-175
Friend has a pristine condition 7800GTX BFG 256PCI-E for 200$
Highest overclockable memory in 512 pairs
and the MB i was sorta waiting for the ATi 580 MB chipset to come out but i hear it might come out in "june" so if thats the case it will either be the Asus A8N32 or the DFI SLI-DR Expert

the 165 or the 170 but listen to rich he has the 170 and he oc's like crazy!

I have the 175 and it max's out at around 2680MHz even when using multipliers as low as 9.5x at 282MHz
