HI.

I have an AMD Athlon 64 3200+ processor, and I intend to upgrade to a better one. The big problem is that my MB uses sckt 939.......can't really choose from many processors.........I have 2 offers:

1. Opteron 165 OSA165CDBOX (Socket 939) - 200 USD
2. AMD Athlon 64 4600 +X2 (Socket 939) - 220 USD (can't upgrade to AM2)

Need help,
TNX.

All we need to know is if you are going or Willing to Overclock. Then the answer will clear.

BTW, what is your Motherboard??

If you're into overclocking, go with the Opty. The 165 is available for $155 at the Egg.
If you're not going to OC then go ahead with the 4600, if you managed to find one.

I'll second that - the Opty is ace for overclocking

yes, I'm also willing to overclock. Is it good for gaming?
My MB is a A8N SLI-SE, 2*6600GT, 2*512 DDR 400,2*160GB seagate/maxtor SATA II, sound blaster audigy

With 1.8GHz stock, the Opty 165 is not one of the most impressive dual cores, but it is a very good overclocker for 2.7-2.8GHz and will perform very well. However, you need to stress your motherboard around HTT 300, play with timings etc, while with the X2 4600+, you have a stock 2.4GHz chip which will not bottleneck your gaming setup. Most probably will do 2.6GHz without any problems if you want, so overall, I'd go with the X2 4600+; have had an Athlon64 3000+ before my 4200+ and a 9X multi is not that comfortable for OC-ing a S939 CPU.
