@Lutfij - they're over the price limit for this article.
@stasdm - SLI - it's a trick nVidia pulls to make money from every mobo sold (with SLi support). Mythical or not, intel's PCHs DO NOT support SLi by default - they do not support SLi at all. It's all by means of nV's driver and BIOS-included string. Everything is supported by the fact that PCI-Express has enough bandwidth to sustain two cards - that wasn't exactly always possible with PCIe 1.0 lower bandwidth on previous-gen chipsets. About SATA 6G - most of the crowd won't utilize even half of the SATA ports at all. If they will, then probably they'll treat them only as additional sata ports with no regard to their speed. Enthusiasts will attach their SSDs to PCIe in extreme cases or at least to intel's own controller, which in turn handles SATA internally in PCH without using PCIe. External controllers are out of scope for 99% of the crowd, mind you. For example - show me PCIe based 4x SATA (or SAS, for availablity sake) controller with RAID 5 support below 300$. Any? Don't think so, save one crappy LSI. It's budget side, man. If you want top-of-the-line, get server board for storage and second, gaming, or performance rig, but that's not what's this article about.
@Author - Thank you for great comparison. Too bad it ended on counting what does not work on the boards. It seems that atm intel and ASUS have the most mature and reliable products. However, I'd still wait for second-gen P67 boards (in Q2?), before upgrading. Still wondering what to do with my 1366 rig.
