Problems w/ Jack, looking for good soundcard

-965G intel chipset
-DDR2 800Mhz 2x1GB.
-6400 Core2 duo
I decided to see if I can get jack working on my home system (as well
as a few audio editing programs), when I began to realize that I was
going to have a few problems.
jackd -Rv -d alsa
lmms and ardour both had static with the notes. Doing some reading,
it sounded like it was most likely latency.
Some fooling around later, came up with jackd -Rv -d alsa -d hw:0 -P
-o 2 -i 0 -p 1024 -n 2
(varied around with -p some), and upgraded from 22.214.171.124 to
2.6.24-rc3. That made the static about 50% better.
When I did a bit more digging, I came across a post mentioning that
hda-intel is not well documented and does not work well [advised to
set periods to 3 "-n 3", as well as position-fix to 1], but the
suggestions never made any noticable difference.
Giving up on quality for a bit, decided to try my luck with the jack alsa plugin
Created /etc/asound.conf with the following
Trying to use -Djack in aplay and -ao alsa:device=jack in mplayer gave
me unsupported format errors. I created the following to work around
that (Could be wrong, little experience with asound)
Using that, I cound get either 6 seconds of sound, or 12 seconds of
sound (Varies by how long the period is on the jackd command.
Doubling it gave me 2x as long audio).
Anyway, I was wondering if anyone else has a few pointers to offer
me. One thing that did catch me offguard is I did not realize that
the hda-intel soundchip had any problems from the alsa site. I've
been doing some googling but I was unable to really find any way to
determine how capable any particular audio device is. I did like how
the "Turtle Beach Montego II" soundcard looks, but I want to learn
more about what I should be looking for before I continue
