Comment:
Hi, I'm not too sure if this belongs here but oh well. I'm looking to build a new PC, and I'm a bit torn between getting a socket 939 mobo or a (more pricey) AM2 mobo. Are there notable differences between the two? I know each type accepts different types of processors, but is it worth forking out for an AM2? 939's are notably cheaper on ebuyer.com, and I have quite a tight budget.
The only main diff is DDR2 support, other then that there is no preformance diff between the 2. I'm skipping AM2 and waiting for AM3 myself which should be out by next year sometime and that will offer quad-core support along with DDR3.
Though theoretically, the DDR2 must offer double the bandwidth of DDR, it does not come even close to that expectation on the AM2 platform. At higher CPU speeds, the difference just about begins to show itself. But for this difference, would I invest in a AM2 ? I would not.
I'd still go the 939 way, considering there is nothing like a day-night difference between 939 and AM2. But, if you are looking at an upgrade a year or so from now, the obvious choice will be AM2. Besides, who knows if DDR will still be commonly available (and not cost a bomb) a year from now?
So, from an upgrade perspective - AM2. From VFM perspective as things stand right now - 939

Fried PSU => my 2000+ XP, mobo, mouse and 9600XT are also fied. Damn those light-weight high wattage PSUs!
"Though theoretically, the DDR2 must offer double the bandwidth of DDR"
Why do you say that? The "2" in DDR2 doesn't mean the bandwidth is doubled, it means it's the 2nd phase in DDR technology...it basically picked up where DDR1 left off.
Had DDR 800 existed,the story would have been been different, of course. But then, am comparing the max DDR that needed to be put on a stock 939 system and that on a AM2 system.
But in practice, given the narrow difference between 939 and AM2 in performance, I'd still buy a 939 CPU and spend that extra money on more RAM instead. Or just buy a nice wireless k/b and mouse :)
