Asus P8Z68-V PRO vs NON PRO for overclocking and onboard audio?

[silvon]

I would like to be able to overclock a 2500k to 4.2ghz and have it last for at least 3 years. The build will have one 7200 rpm drive, one Sata3 6gb/s SSD, and a single graphics card. I will be using onboard audio. I have NO interest in SLI or crossfire.

Question 1: Is there any reason that the Pro version would be a better overclocker than the non version? From what I understand, the pro and non pro versions have the same number power phases? Or is the circuitry on the Pro version better?

Question 2: They both have the Realtek ALC892 onboard audio, HOWEVER, the pro version Also has "DTS Surround Sensation UltraPC" and "Absolute Pitch 192kHz/ 24-bit True BD Lossless Sound". Will these features make any difference noticable difference for gaming if I am using onboard audio?

I chose the P8Z68-V over the PRO version.

I found the -v had everything I would want, can still 2-way SLI, and has all the key features of the PRO version

I am mulling over the PRO vs non-PRO as well. The only difference I can find is that the PRO version has 2 more SATA III (6 Gb/s) ports than the non-version does. The PRO version also supports SATA III raid, not sure if the non-pro version does.

So I went with the non-Pro version. Put the mobo on auto overclock and got 4.3Ghz on a i5 2500K using an Arctic Cooling Freezer 7 Pro.
