I went with the Asus P8Z68-V Pro myself. So far, I'm loving it. The layout is great, excellent overclocker, runs pretty cool with stock heatsink and the UEFI BIOS is very nice. The Asus AI Suite II software is pretty nice too, but I don't use it much.
PS. I really like being able to have a discrete graphics card and use QuickSync.
What ticked me off from jumping on the V-Pro is that it doesn't have the PLX chip, so you cannot utilize all PCI-E lanes if you have all slots filled. I know, I know...will never have those slots occupied, but the lack of it just ticks me off.
