I'd forget the Intel D 830 in favor of the
new 65 nm 900 series aka "Presler"
dual-core Intel CPUs. These consume
less power and thus run cooler than
the previous Prescott cores.
The Presler can also be over-clocked
much more than the Prescott cores.
And, because I have so much experience
building powerful workstations with ASUS
motherboards, I'd strongly recommend
that you give serious consideration
to either the P5WD2-E Premium
or P5WDG2-WS motherboards:
http://www.asus.com
Both have the 975X chipsets with
1066 MHz FSB, lots of over-clocking
capabilities, and too many other
features to mention here e.g.
dual-graphics cards like Crossfire.
Both can take you all the way
up to the D 955 with HyperThreading,
which computes 4 threads in hardware.
We learned back in 1997 to start
with an excellent motherboard,
because it is like the foundation
for a multi-story house.
AnandTech.com has a detailed review
of a 3.0 GHz dual-core Presler which they
over-clocked to 4.6 GHz on the
P5WDG2-WS motherboard:

We'd also recommend that you
start with Corsair XMS DDR2-800 /
PC2-6400 RAM. It's truly superb
memory. I believe there is a
newer model with the "UL" suffix
i.e. "Ultra Low" latency, which
would come in handy if you want
to over-clock a Presler a lot.
If you do plan to over-clock a Presler,
bear in mind that it's very easy
to "starve" it of memory bandwidth.
If you plan to stay with stock speeds,
the Corsair Value RAM is a good deal.
AnandTech.com came to the conclusion
that the Presler on the ASUS P5WDG2-WS
motherboard is truly an outstanding performer.
The only key points to remember are
that the D 955 with HT does not support
SpeedStep, whereas the D 950 supports
SpeedStep but not HT, like all the others
in the 900 series below it.
We are planning to install the D 950 in our
P5WD2 Premium, because we like our
machine to throttle down when it's idle.
Lastly, consider definitely installing a
superior heatsink/fan unit, e.g.
ASUS VR Guard Series:

We've isolated a serious "seating" problem
with the stock Intel heatsink/fan: the cure
is a heatsink with a proper backing plate.
Now, our Intel P4 640 idles at 91-93 degrees F.
If I'd had as much successful experience
with AMD CPUs, I'd probably be recommending
them to you here instead
I hope this helps.
GOOD LUCK!
