Audio Performance
The Realtek ALC-660 HD audio codec was tested with the recently released 1.31 driver set. The Realtek DirectSound audio drivers do not support more than 32 hardware buffers and the OpenAL 1.1 drivers do not support more than 30 hardware buffers at this time. So, the scores cannot be directly compared to the HDA Mystique 7.1 and Creative Labs Sound Blaster X-FI cards in the benchmarks. The Realtek OpenAL 1.1 driver increases CPU utilization up to 20% more than the Realtek DirectSound drivers.
However, if you are a serious gamer, then a dedicated sound card is still a requirement to ensure consistent frame rate averages across a wide variety of games. We noticed in previous testing of our Battlefield 2 and Half Life 2 benchmarks that the Realtek HD audio codecs would cause stuttering in intensive scenes. The 1.31 driver release has now eliminated all stuttering in our current benchmarks while improving performance across the board except in Serious Sam II. We did not notice the same performance degradation in Serious Sam II with the 1.31 driver set and the Realtek ALC-882 codecs on the Intel chipset boards. We are still investigating this issue.

I see, I'm still interested to see how this Epox board overclocks, I look forward to the Anantech review. If its priced similar to the Asrock Sli but with better voltage options I will get one despite it being x8 x8 ... thanks for the info.UJMA - Saturday, March 4, 2006 - link
fantastic!!! I rate Epox boards highly, I'm waiting for that particular board to make an appearance in the UK ... I look forward to your results!Redrider - Saturday, March 4, 2006 - link
I am looking to build a system for my 15 year old son who does video editing as his system stressing function, not gaming. We do video editing on my own aging but still quite nice FIC AU13max, Athlon2500+, All-in-Wonder 9700pro, 1GB (2x 512)PC2700, system that I built 3 years ago (my only other previous build). I want to build a system that will be good for video editing primarily but provide for gaming should his gaming interest change from his Playstation2 to his PC. I would build my own system and pass my old system down to him like I did last time, but really like the DVR/home theater I have set up with my TV, JVC 9010VBK receiver, and AIW AGP card.Anyway, things sure have changed since my last build! I could use a bit of guidance. I am considering this board and would like advice on the least expensive (as a baseline, I will work my way up from there budgetarily) CPU, memory, video card, etcetera that would serve the aforementioned needs.
To add a bit of complexity to my question (I hope this off topic diversion is ok) I had been considering a DFI LP UT NF4 Ultra-D mainly for the future potential if he gets into overclocking and such as well as the cool factor with a uv lighted case. Some reviews gave this poor marks for stability at the default settings which sent me looking elsewhere like here. Does the X2 support of the ASRock 939SLI32 warrant going with a dual core and this board for multitasking capability?
Thanks for your assistance.

my $.02I just RMA'd a defective Ultra-D. The power requirements are very high, as it is capable of severely overvolting your hardware. It is also a very advanced board and may be difficult to use in many situations. Read at dfi-street.com before purchasing system components if you're serious about this avenue.
Perhaps he would be better off with a less demanding, more user friendly board like the Asrock board or an Asus offering.

Thanks for the heads up. I was a bit apprehensive about the reviews referencing compatibility issues on the DFI. This ASRock seems interesting. Asus seems like people either love'm or hate'm. I tend away from mainstream as evidenced by my FIC Mobo which appears to be one of the last of the line. I guess I'll keep on looking to see what I come up with.If I go with the ASRock any component suggestions? Any other specific components that I should avoid?

Great to see the new way of presenting the gaming benchmarks. The "min" numbers are especially useful. Nice and easy to understand as well. Keep up the good work! I hope you will continue to use this in all your gaming benches. With the reports/speculation of Nvidias next high end offering being close to ATIs X1900XTX in the sense that it will beat it in some and loose in others this extra info might be the decisive factor.Missing Ghost - Thursday, March 2, 2006 - link
I don't like it. The layout is not very good. The chipset heatsinks look crappy. It seems like the southbridge heatsink is too high and will be in the way of expansion cards. And why a 20 pin power connector? I want 24 pins, especially because this board supports sli. I think I can find better for this price, but maybe that's because I don't care about 16x pcie slots.kelim - Thursday, March 2, 2006 - link
Can anyone confirm what (if any) Zalman HSFs are compatible with this motherboard?Gary Key - Friday, March 3, 2006 - link
Zalman CNPS-9500 - YesZalman CNPS-7700 - No
Zalman CNPS-7000 - I do not have this item but looking at the measurements it would be extremely close, taking the measurements off the 7700 unit in place it might fit but just as easily might not.

Thank you good sir. The 9500 is what I'll be coupling with this baby.
