I would argue that with current product offerings, DDR3 itself is lame. I
see no reason to go for DDR3 at this point, given the high cost and
marginal--if any--performance boost at current frequencies and timings.
While you are indeed correct in that Intel boards have legendary stability,
they do have other issues...including bland feature sets, and they serve as
a platform to push Intel's own agenda. The Intel P35 boards I've looked at
lack any PATA, PS2, serial, and parallel ports. For some usage scenarios,
it
isn't yet possible to rid a board of all legacy components.
Same was said of first generation DDR2 vs DDR. DDR3 while lame in
performance vs hype and expectations, is still the future. The Intel retail
P35 does have an add-on Marvell PATA controller and a serial port, but does
ditch PS2 and legacy parrallel printer ports.

As I stated in a previous post, SeaSonic gets my vote as well. But I'm not
sure where you're coming from with your implication that efficiency has
anything to do with output. Power supply capacities are rated on OUTPUT,
not
input, so a 60% 500W power supply is going to deliver the exact same output
as an 85% 500W power supply--it will just do so wasting 25% less energy.
You
see the same thing in HVAC equipment...a 10 SEER 5 ton unit provides the
exact same cooling capacity as a 16 SEER 5 ton unit. Efficiency should not
be considered as having any relationship with the ability to do work.
Greg
In theory you are absolutely correct - efficiency should have nothing to do
with output. However more efficient power supplies = less heat produced, and
an ugly reality that many brand X power supplies hide in the fine print is
their highly touted wattage output rated at a certain, unrealistically low
operating tempurature.
