QUOTE(redclawkefar @ Aug 20 2005, 09:05 AM)i wouldnt consider it a waste... yes the opteron is a bit more expensive, but the k8w is a system built for stability and hardcore usage.
and adding a second chip later will be a wise investment.
Well he was to decode some HD movies, so I guess that server services like 24/7 reliability are not needed.
yekat also noted, that it does not intend to upgrade in the near future, so if he wants to run a single CPU setup, he might save some money by buying e.g.an Opteron 148, which costs around the same price as one 246.
But still, if the used program is multi-threaded, a dual 242 setup can be faster.
Yekat should investigate that. Or if he does not know how, at least name the software.
Your mentioned DDR400 disadvantage is not really an issue. It does not depend on the type, but the revision. All Opterons with at least C0 revision can run DDR400. The Opteron x46 types were introduced first with that revision, hence the often red confusion with DDR400 support. Nowadys most sold Opterons are already CG revision, even in the 240 or 242 range. So as long if you buy at big resellers and not e.g. used ones at ebay, you will have DDR400 support.

IF the software is multithreaded, then maybe the ideal system could be an Athlon X2 system ?
The X2 3800+ is available for ~$400. That might be also the money amount you can get for selling the old K8W S2885. You do not have to use expensive registered RAM, and the CPU performance is nearly the same like a dual Opteron244 setup, besides the missing NUMA memory bandwidth, which is not a big performance loss.
If you like, you can also overclock to gain a bit more performance. Of course this is only an option, if your are using your HD stuff privatly and not professional.
