Try the opteron if you like overclocking and also having K8L drop-in compatibility for a future upgrade.

The Santa Anna 1212 seems like a nice choice. Note user reviews for details.

Also, the quad cores will be Opterons first, so people who go this way and want cutting edge can get one of the low end Opteron quads due in the first half of 2007.

This belongs in the overclocking section, not here.

So it's the AM2 version of the 170. It overclocks well. Not much of a surprise, really, seeing as how well its predecessor did.

Opterons are the most excellent...and best kept secret in AMD processors, as evidenced by all the X2 and FX threads that ramble on, without mentioning Opty's. Too bad more overclockers don't research the Opty's.

How do the Opterons compare to the C2D's? And why are they so over clockable, compared to the X2's? Is this because they have a different architecture?

C2D's are 65 nanometers, Opterons and X2's are still 90 nanometers. The overclocking limit for clean 90 nanometer dual core AMD's is about 3.05Ghz on high end air cooling. Check out the following THG article:

As server / workstation class processors, AMD Opterons and Intel Xeons are yielded from cleaner areas off the same wafer material as desktop CPU's, so they're binned for stability at lower voltages. Consequently, this allows for operation at lower temperatures per clock than desktop CPU's, which is an important consideration for servers. Fortunately for the rest of us, this also makes them the best overclockers.

Opterons and Xeons are the same architecture as their desktop counterparts. C2D's are a major improvement in architecture over X2's and Opterons, as explained in the above article.

Hope this helps! :D

so you wouldn't play games with a Opteron, they're more server based?

No no, hehe. They are just more stringently selected so they CAN be reliably used for those sorts of things. They play games fine, :)

AMD Opteron 1210 Santa Ana 1.8GHz Socket AM2 Dual Core Processor = $175 (newegg)
AMD Athlon 64 X2 3800+ Windsor 2.0GHz Socket AM2 Processor Model = $122 (newegg)
The Opteron is $53 more expensive.
The differences are:
Clock speed: 1.8GHz Opteron VS 2.0GHz Athlon
Cache: 2 x 1MB Opteron VS 2 x 512KB Athlon

Is the Opteron worth it?
I am hoping that the Opteron will overclock higher than the Athlon, or at least equal it?
Is the performance difference noticeable? (cache difference)

I have a 50% overclock on my 3000+ @ 2.7GHz and want to do the same with the Opteron, and judging by this thread, it seems possible :D
