Hello,
I own a P5KC since 5 months and it works faultless (Vista Ultimate 32 bits)
with an Intel Core 2 Duo 6750 @ 3.4 GHz (stock fan and voltage), and 2x2GB
DDR2 Corsair PC6400 (800MHz) memory @ about 920 MHz (5-5-5-1

with 2.0 V
instead of stock 1.9 V (there are 4 sockets for DDR2, and 2 for DDR3, but
you cannot mix DDR2 and DDR3). Take note that about 3.3GB of the 4GB ram are
available for the user (this is not a bug, and is OS dependent: Vista uses
part of the RAM depending on the hardware installed on the MB; google if you
want to know more).
I don't use DDR3 (too expensive - certainly for 4 GB - and no real
performance gain at the moment).
I use a Nvidia 8800GT graphics card with 512 MB.
I also use on-board sound and (wired) Gibabit controler.
Connected are 2 SATA and 1 IDE HD, 1 SATA and 1 IDE DVD burner.
Other P5Kxxx models support ICH9R for full Intel raid (P5KC has non raid
ICH9 with the much less flexible JMicron raid 0/1 controler [only supporting
2 disks: 1 SATA and 1 eSATA], and I don't use it, which isn't a big
trouble).
Also, there's no on-board Wifi of any type; some other models have it, but I
don't know if they support (pre-)N protocol or only B and G.
Note that the single IDE controler connector couldn't be placed at a worse
place than it is: if you're unlucky with your (IDE) HD placement in your
case, a standard length IDE cable will not be long enough (look at P5KC
pictures at Asus site, or download the manual)
If I had to choose a MB now, I would evaluate the other Asus models (P5Bxxx,
P5Kxxx, ...) supporting Intel chipsets (which implies dual graphics
capability with ATI's Crossfire, and not with Nvidia's SLI); also, support
of raid ICH9R would be nice.
Anyway for the P5KC I own, performance and stability are at the moment the
biggest positive points.
