Personally, I think the P5K's are too expensive and they have features I just don't need. I've generally been partial to Asus boards in the past, but I decided to give the Abit IP35 Pro (I use RAID0) a try and so far I'm glad I did. If you're used to Asus, the board's layout and BIOS have a different feel. The BIOS is just a matter of adjustment, but the layout has a few quirks that I don't like.
1) The right angle SATA ports are a complete pain in the ass. Sure, they don't interfere with my 8800GTX, but I also pretty much have to remove the card to get to the SATA cables. With straight SATA ports you can use pliers to gently insert/remove SATA cables in between your add on cards.
2) The 4-pin molex for supplying additional power to the PCIe 16x slots is smack dab in the middle of the expansion card slots... Not an easy place to have to run a power cable, and a really bad place if you want your wiring to look pretty. It's possible that this additional power is only necessary if a second PCIe card is installed for Crossfire, but the manual does not seem to indicate this one way or another.
3) floppy drives are almost always at the top of the case, why did Abit put the floppy plug at the bottom? I don't own a cable long enough to install my floppy... Luckily Vista recognizes the RAID0 array unlike XP that would have required me to do the put the RAID drivers on a floppy.
...all of these layout quirks are surmountable, but I wanted to make note of them.
At $180, it still isn't the cheapest of boards, but still a good chunk less than then the comparably equipped P5K's. So far, I have not had any issues whatsoever with the board, and I've easily managed a mild OC with my E6600 running 3.0GHz. My main focus is stability and a bit of a speed bump, not to achieve the world speed record. I'm fine with 3.0GHz with zero hassle, but I'm sure I could tweak it much higher if I really felt like it.
Overall, I'm happy with the board and wouldn't hesitate to recommend it to anyone looking for a mid-priced, easy overclocking board with a decent (and usable) feature set.
edit: If you have no intention of running SLI, don't bother looking at the 680i boards.

I imagine you will taking back that recommendation at this point?
