Help required: Choosing a decent P35 MoBo for use w/ OSX, Asus P5KC or Gigabyte GA-P35C-DS3R? Or...? Options

[3phemeral]

Update: I've ordered everything. I settled on the Gigabyte GA-P35-DS4 but am still to receive it. Other parts as mentioned.
Yet another update: I've received everything i ordered [but the graphics card was damaged -> RMA] and everything runs smooth, including OS X. After a bit of fiddling about, everything on this board seems to be working: SATA by turning on AHCI in bios, IDE [natively], sound [ALC889A, for fix for this, read on], ethernet with the realtek patch, ... The only thing i have not tried yet is firewire [yet this is listed under System Profiler] and eSata, but i don't even have the eSata bracket installed... Even sleep is working [w/ 10.4.10, 8.10.1 kernel] which i find great! Very pleased with this board If you ever need any help on getting anything working on this board [besides sound, hehe], just ask away
Yet another update 2 [to be updated]: Sleep not working anymore. Don't know if it's a hardware/bios/software change. I'll investigate them all when i've got more time. The latter seems most likely, but also most complex to investigate.

Hey all,
I'm looking to put together a new PC. My main issue is the motherboard. The 2 I have my eyes on are both P35 boards [for future 45nm CPU support] w/ DDR3 RAM support, although the latter isn't too important: The Asus P5KC and Gigabyte's GA-P35C-DS3R.

Which of these would you recommend? What kinda problems would i be looking at trying to install OSX on either boards? And getting LAN, ... to work?
I'm aware that the ALC889A audio controller on the Gigabyte has no OSX support at the moment, while the ALC883 on the Asus should work.
Other motherboard suggestions are welcome, but i would like a board w/ a P35 chipset.

The rest of the specs will be something like this:
CPU: C2D E6750 [to be overclocked ]
RAM: 2GB 800/1066 MHz RAM, yet to chose which specific one.
HDD: 500GB Samsung SATAII Spinpoint(?) most likely
GPU: Still to decide. Most likely some 7600GT
DVD: Still to decide.
Already have: Antec Sonata II case w/ Corsair HX520W modular supply and Zalman CNPS9700 CPU cooler.

Thanks in advance!!

Hi guys, I'm new on this and I'm having problems with the Audio. I have the GA-P35-DS4 and a 10.4.9 version os the OsX. Everything works besides Sound, the Raid of the ICH9R, and the second monitor (Dual monitor) .

I would like to start with the audio. I downloaded all the kext I found about ALC889 but nothing. On onership I should put "Read & Write" ? I installed the AzaliaAudio.pkg and AzaliaAudio2.pkg. No idea what else to do. I restarted, got errors and nothing. Next boot nothing too. No audio. I did some stuff on the Terminal and everything looks ok but still nothing.

What it should be the normal steps (step by step for a new on OsX ) to install the audio?

Thanks on advance!

Spec:
GA-P35-DS4
Intel Q6600
WD 250HB S-ATA
X1950 512MB Dual DVI
2GB Ram 800

As posted several times before in the thread, you need this kext, which was originally posted here.

In order to get it to work:
extract the files from the zip [under osx simply double click on the .zip file].
Open up Terminal [Applications -> Utilities -> Terminal] and type the following [bold text: text to type in Terminal. Safest way is simply to copy/paste to terminal]:

1. sudo -s (enter password)  <-- Gives you administrator rights
2. cd /location/of/kexts , for instance cd /Users/your_username/Desktop if you've extracted the files on your desktop
3. cp -R ALCinject.kext /System/Library/Extensions && cp -R AppleHDA.kext /System/Library/Extensions  <-- This copies the files to the 'extensions' folder
4. <-- The next step will set the correct permissions for the files -->
5. chmod -R 755 /System/Library/Extensions/ALCinject.kext && chmod -R 755 /System/Library/Extensions/AppleHDA.kext
6. chown -R root:wheel /System/Library/Extensions/ALCinject.kext && chown -R root:wheel /System/Library/Extensions/AppleHDA.kext
7. rm -f /System/Library/Extensions.*
8. diskutil repairPermissions /
9. <-- Now reboot your computer: -->
10. reboot or sudo reboot 

Hope it works,
