Some points for BloodWolf to consider:
- Decent low-latency DDR2 RAM costs well over £300.
- AM2 CPUs are not in stock yet.
- There is only one aftermarket heatsink for AM2 at the moment which is also not in stock.
- Motherbaords lack variety (e.g. no DFI overclocking boards) and of the ones that are available, there is hardly any feedback on the forums.
- Motherboards also appear to be buggy, look
here for example.
- Also bare in mind that the performance difference between Socket 939 and AM2 is negligible.
- Socket 939 is a mature, reliable and proven system - it's also much cheaper too!
- On the otherhand, AM2 is more future proof and seems to have a better upgrade path, AFAIK AMD will be releasing their new 65nm processors on socket AM2.
I wouldn't want to be an £850 guinea pig tester for new gear. But someone has to take the plunge into the AM2 pool, and if BloodWolf chooses to be one of them, then Semi-Pro has given a good AM2 spec above.
I'm not saying Socket 939 is better than AM2, I'm just giving the OP some points to consider when deciding whether to choose 939 or AM2 from the perspective of how things stand today.
