So after testing it for 2 days, there are a few issues that really annoy me:
1) Vcore fluctuation. Watchin CPU-Z jump from 1.728v to 1.792v while IDLING is rather uncomfortable. My Gigabyte K8NS-Pro almost NEVER twitches. I realize that the DFI increases vcore during load, but even @ load, it fluctuates 0.02v, and very frequently..
2) vDimm fluctuation. Jumps from 3.30v to 3.34v while in BIOS... Don't know how much it dips while doing memtest.....
3) High pitched squeeking noise when booting WinXP during resolution changes. Very annoying and rather loud. I assume they're coming from the coils, and I think I've read about a fix somewhere by taping down the coils?I've tried 2 diff CPUs and 2 diff sets of ram, happens everytime I bootup whether overclocking or not, never happened on any other mobo I've used. PSU is an Antec Tru550. Probably an issue related to this specific board, but it gives you an idea about DFI's quality control

4) Build quality: the caps used are "decent" I guess, they come from United Chemi-Con which should be made in Japan, but most of the MoSFETs are small and no name, which is probably what's causing the vcore and vdimm fluxing. MoSFETs also get HOT while underload, but I guess it's quite normal for all boards, DFI should of included heatsinks with it though since it's aimed @ the enthusiast market....
All the caps on the K8NS are made by Nichican which are high quality made in Japan, and the MoSFETs are big, made by NEC. I believe the Epox board uses Sanyo caps, and the MSI uses....??
5) Northbridge heatsink has thermal paste underneath it, which is GOOD, but it desperately needs a fan. If you turn the vChipset up and run the board outside of a case without air circulation, the thing gets HOT!
6) There is no difference in overall performance against other boards. I benched both the DFI and my K8NS-Pro in 3dmark05 and CS:S stress test using the same equipment, settings, everything. DFI was 7points faster in 3dmark, and the K8NS was 1FPS faster in CS:S.
Don't get me wrong, the DFI is a good board, but it isn't the HOLY GRAIL that most people think it is, and it probably WON'T get you a higher CPU overclock or +1000 3dmarks. I see all these people who were waiting for the DFI to switch to A64, or thinking that the DFI can hold them off from S939, but I just don't see this being the case. I've also seen quite a few people having issues with the DFI board..
Personally, I despise the vcore fluxing and the relatively "cheap" components used... I actually needed 1.728v to run my 3200+ mobile stable @ 2.52Ghz whereas my K8NS only required 1.696v. Maybe the board I tested is a dud?
On the plus side, the endless BIOS options are nice, and so are the voltage options. But frankly, almost all these tweaks can be done via A64Tweaker + a soldering iron... Of course, people will say how unstoppable the DFI is when paired up with TCCD ram, but I won't get into that right now since A64 and memory is such a hit and miss issue.
Again, these are my own observations and opinions. I know all you DFI lovers will probably start flaming this thread, and I don't care. Just want to inform potential buyers of certain issues. NO motherboard is perfect.
