First thing I did after basic OS install was update the BIOS, which is very easy thanks to Intel product support pages online. After reboot, I installed the latest motherboard/chipset drivers from Intel (it's good to download them and store to USB stick or CD ahead of time, otherwise you'll have to use the driver CD to get the NIC working and get online to download drivers). Reboot and then latest drivers for the gtx580. etc. then test stability. then overclocking fun.
It can be over-clocked by adjusting the max turbo settings, but it lacks fine tuning of voltages and it locks the max base frequency of the CPU. (I'm not sure but I think this is normal for Sandy Bridge and it applies to all P67/Z68 motherboards). I settled at max turbo setting 45 for one to two cores, 44 for three, 42 for four cores. Hyperthreading enabled. Works great. I like it this way for a number of reasons. I have all the power management features enabled. When idle it sits quietly and cool at 1.6ghz .99v. It can spike up to 4.5ghz/1.26v with up to four threads cranking along (hello games), hover around 4.4ghz under heavier loads, and fully stressed it cruises at a steady and cool 4.1ghz/1.26v (8 threads maxed!). It does all this without ever going over 1.34v/55C which is well-within spec and I haven't even tweaked the voltages, just let the motherboard handle that automatically on default setting. I did raise the wattage for burst and sustained mode, but only modestly (134/130). I left the cpu max amperage at 97. I could push it harder but it's working well this way. It seems very efficient and performance is excellent.
I am getting 4.4ghz-4.5ghz consistently in games, which is great. Performance/feel is smooth. Handbrake rips average about 150fps (from a mounted dvd iso from WD green 2tb on eSata 1.5gbps to output to internal Sata 3gbps WD 1tb Black, format .m4v file with ipod 5g support, 8 threads at 4.1ghz), which ain't bad. I'm not sure how much of a gain there would be to push it much harder, to have all cores running at peak all the time. I wouldn't mind higher clocks full-time, per se, but this way is so efficient, cool, and stable, and with very snappy performance.
(NOTE: see the edit at end, I got MUCH better overclocks later!)
As to features, I have used the eSata port on back and it worked flawlessly. I haven't used the SSD caching("smart response technology"), the USB3, or tapped the potential of the SATA 6gbps yet, or tried the hdmi or displayport video ports that serve the CPU's integrated GPU. Intel supplies Virtu software which is supposed to make the onboard (sic) video work alongside an add-in card and supports quicksync. So I look forward to trying that, when and if I find a likable video encoder software that's quicksync accelerated. Also, the intel video is supposed to handle HD content really well, but I haven't tried it. The Intel NIC works like a charm. Onboard sound is just fine for onboard sound. My only real complaints are that there's only two SATA 6 ports, so no RAID 5 in mode SATA 6. And you can't use RAID and AHCI modes simultaneously. It's one or the other. BTW if you have a hard-drive with cherished data on it and attach it, enable RAID mode in BIOS and then boot up it might just wipe that drives partition in the blink of an eye! Happened to me once. Luckily, there wasn't anything valuable on there. Just be careful with that.
The only glitch is that the system becomes slow and then unresponsive when doing large file transfers to an old WD Mybook external drive when using the Firewire port. Have to look into that. Windows 7 is notorious for being buggy with large file transfers.
Mostly it's all extremely good here. When I setup another monitor with the on-board video and start using quicksync things will really start getting interesting. I'll add that to the review when I have some results.
Anyway, happy camper here. thanks.
I got a little adventurous and pushed the overclock and am having very good results. I raised the max turbo frequency to 46/47 (46 for 3-4 cores, 47 for 1-2 cores). This has resulted in stable 4.6ghz under full load on all 8 threads, and 4.7ghz fulltime in games, with 4 threads on tap. I just had to change a few settings, very easy and intuitive. In the BIOS I raised the max amps for the CPU to 120 amps (from 97 amps) and I bumped up the reference voltage .05v from default, which usually results in .99 volts at idle and 1.30-1.34 volts under load, now results in 1.35-1.4 volts under load, 1.04 volts at idle. Processor power management is set to Dynamic. Max temps 60 degrees C, max Volts 1.4. This is much better than what I was getting with the prior setup, and it's still within a reasonable margin of safety for the motherboard and cpu. The dynamic power controls still work, even when fully loaded it's not always at 1.4 volts. The Sandy Bridge tech seems extremely smart and efficient in this way. The one thing I haven't figured out yet, and it's kind of a sign of the strength of the technology design, is that sometimes when all 8threads are working 100% (like crunching superPi 32M) the turbo will sometimes disengage, so the cpu drops to the base frequency (3.4ghz by default). This throttling effect must be the motherboard/cpu knowing when to protect from overload. I'm be tempted to override this function by adding more current but it doesn't seem to effect real-world performance much, only when doing 100% loads like Pi or Prime95 or Handbrake, and I've never seen it happen in games (two cores/4 threads at 4.7ghz). If it protects the motherboard and cpu, I can live with it. My handbrake rips with the new OC average around 200 fps, with spikes up to 300 fps. When throttling to 3.4ghz the fps cruise at 150-200 fps. The throttling kicks in about 50% through the rip and then it goes up and down occurs in fairly regular intervals of 15-20 seconds at 4.6ghz and 35 seconds at 3.4ghz, up and down. CPU voltage fluctuates accordingly in the same fairly regular pattern, from 1.24 to 1.36 volts. The pattern is so regular and performance is barely effected, so it doesn't bother me. Besides, handbrake is the only real-world app I use that stresses the cpu 100% on 8 threads, and I plan to use quicksync in the future, so I'm not too worried about the slight throttling and I'm glad it's there keeping my parts from cooking. Games run so good at 4.7ghz with 4 threads! I'm well pleased. I might just call it good at a solid 4.6/4.7ghz on this vanilla Intel motherboard!
When the next gen of SATA 6 SSD's are down in price I look forward to a RAID 0 config, that should be mindblowing.

In my case, when I put in an i5 3470, all I got was a 3beep memory error code. Pissed me off quite a bit. To fix this I had to buy a $35 Celeron processor and format a usb stick to iflash an updated bios to the board. To avoid this somehow, the seller will have to tell you which bios version is on the MOBO, good luck with that. The bios should be version 40 or later (I used version 43)
After the update, I put the 3470 back in and everything worked great.
the specs are as follows:
1-DVI-I Dual link port (so you can use a dvi to vga adapter if needed)
1-intel display port

additional connectors (near the memory and above the processor) for the front and rear fans respectively.
My other gripe is with something I haven't totally checked out as yet but so far the Virtu software for my unlocked i7 2nd gen processor refuses to install, it claims there is no onboard GPU present!! Now I've read where this may be due to me having already installed a video card, but come on, isn't this software supposed to be able to decipher between video cards and the onboard GPU and choose which to use regardless of which one's port my monitor is plugged into??!!! I can't be bothered right now but one of these days I'm gonna uninstall the video card and try the alternate set-up using the onboard GPU of my processor and gain attempt to install the Virtu software.
Oh one other thing, the Integrated Assistant software doesn't install easily (if any at all). After downloading it, I had to unzip it to a folder from which the executable file worked but wasn't really installed in the traditional sense to the computer. I ran it and tried, with some effort, to update the BIOS as it was reportedly out of date...a lot of problems ensued after a "reportedly" failed attempt at my BIOS update...my Intel Desktop Utility software (monitors the temperature etc., of the system hardware) stopped working, and my computer crashed so I had to "system restore" it. After running system restore, surprisingly enough the BIOS was actually updated but the Integrated assistant software no longer worked as it claimed it was no longer compatible with the motherboard (sigh). I no longer use it (ppbbt!).
Outside of all this, it's an ok mo'board.

Application is use as a digital audio workstation (DAW), running Reaper 4 and Audacity. Interface provided by a PreSonus FireStudio Project over FireWire 400 (IEEE 1394A). One of the prime reasons for selecting this particular mobo was that it has an on-board 1394A port, and I was hoping that it would provide a solid connection between the DAW software and the PreSonus.
Instead, we spent a week trying every driver combination and software rev for the interface, all to no avail. We could easily get a connection, it just popped and crackled continuously, both on recorded tracks (input from the PreSonus) and playback through the PreSonus. I've probably read 100 entries on 50 tech websites and know more than anyone would ever care about FireWire drivers and Windows 7.
We ended up pulling a PCIe FireWire card from another machine and, voila, problem solved. This card is built using a TI chipset, but probably more importantly, a lot of people have success with the TI drivers, which is why we got it in the first place.
Bottom line: Intel needs to put a little more work into their FireWire drivers.
Other than that, the box is a screamer for this work. Even complex mixes rarely put Reaper over 30% CPU utilization. CPU temps were 75C during burn-in (24 hours running prime95), but don't go over 35C during "hard" DAW work.
Even the onboard audio is pretty decent. Fortunately, the board had the latest firmware installed so it is compatible with the new Ivy Bridge chips. Happy so far!
