Default CrossfireX tri 3870: 400W or 680W??? DDR3 or DDR4???

I am considering going tri crossfirex 3870 for now. But I have a couple questions:

1 - I have a fairly new Zalman 600W PSU with lots of Amp on the 12v rail, enough to run an 8800Ultra overclocked together with a Q6600 overclocked as well. Some reviews say that tri crossfirex 3870 consume around 400W at load. I think my PSU will be enough for the tri crossfirex then. But I just want to make sure, because one single preview (hardocp) caught my eye and it stated that the tri crossfirex sucked up 680W !!! Can anyone here tell for sure and help me please? I have absolutely no plan of buying a new PSU.

2 - I was looking at the models available for purchase and it seems that the single chip 3870 uses DDR4 modules and the X2 uses DDR3?! Will that affect performance?

Help pls, been away from ATi too long to know anything...

yes that is my PSU... so it should work? I don't have much more stuff in thePC. A couple HDDs, 4gb DDR2, DVD-RW, three 12cm case fans.

You really think it's worth waiting till june? What's supposed to be out by then? I thought both ATI and nvidia would only release new cards at the end of july or even august. Anything good coming any sooner???
