Does the above boards promise controller support Native Command Queuing
(NCQ) or would I need to purchase a separate controller to have that
feature?
Thanks,

Out of curiosity -- what OS do you run, and what kind of workload do you
have that you think will benefit from NCQ? What kind of throughput gain
do you expect from NCQ? How many SATA HDs are on/in this box?

I run WinXP Pro....very minimal workload as this is my home
pc...spreadsheets, word documents, a little playing around with
photos.....very little gaming, etc. As of now, I have no SATA HD's, but I
believe one of two of my HD's is going south so I figure I'll be buying
another soon.......figured I'd go with a SATA so as of now, I have no
experience at all with SATA or anything related to it. I can get a 160 to
200mb Seagate SATA for a good price and I've read positive reviews on the
drives. While reading the reviews I've seen mention of NCQ having a
performance advantage which is why I ended up asking the question. Maybe you
have some advice? Thanks

I don't think you'll see any gain from NCQ. The primary advantage
of command queueing is the ability to reorder multiple outstanding
commands to minimize seek distances. Unless you have an OS that
supports asynchronous I/O, and a workload that commonly issues lots
of concurrent disk commands, you won't see much increase in
throughput due to NCQ. NCQ is really aimed at database servers
and the like, not at single-user PCs.
For better HD performance, buy a better HD. The WD740GD, at 10K RPM,
is still the king of the SATA HDs. Also, two HDs is better than one;
using one HD for the OS and one for the pagefile does help, and you
can experiment a bit to find the best placement of your frequently-used
data and apps.
