This is a much better review. P5K reviewed by Door4ever was a terrible one, didn't even benchamarked the mobo.

In Crossfire, only one PCIe slot is at 16x. The other is at 4x/1x. Probably doesn't make much of a difference, but still.

Very nice article!
After Ive read it, I decided to buy this mobo. There is only one thing worrys me: does this support nvidia 7950GX2 video card? I know P5B does, but I don't know about P5K...

Do the board have Raid 5 option?
You write "There are six SATA ports on the board for hard disk drives. These ports are implemented via the ICH9R South Bridge. The integrated Serial ATA controller of this South Bridge supports NCQ, 3Gbit/s data transfer rate, RAID arrays of types 0, 1, 0+1 and 5, and Matrix Storage Technology. " but ASUS don't say anything about Raid 5.
Please clearyfi!

One of the best reviews I've ever read. But: (1) the lack of compatibility with DDR3 is not discussed. Thus, if DDR3 prices drop and the issues of DDR3 are resolved users would have to upgrade this board if the want to get the DDR3 memory; (2) the panel layout could be better; (3) four additional USB ports would have been very nice, for the number of external hardware is growing and most, if not all use the USB standard to connect; (4) the P5B numbers look good enough to have merit a more in-depth discussion than that given; and (6) I didn't get a clear idea of why the P35 chipset is better than the previous 965 solution.

There's a debate on the net over the Core 2 E6850 and Q6600 Intel CPUs. I wonder how these would compare using a P35 chipsets on a mainboard like the P5K.

Thank you for this extensive review. I enjoyed reading it very much.
