Well, you should certainly consider this board as an option. However, bear in mind the following:
- the x38 chipset is new, so expect some teething problems
- this motherboard is currently on it's 1st revision
- there's a few beta bios' available, but only 1 official (F3) to the best of my knowledge. Some are reporting problems with most of the beta bios'

Future bios releases may fix some/all of the current problems. However, a board revision may also be required.

On a personal note, I've managed to achieve my target of 3.6GHz on my Q6600 without problem, but need more time before I can provide a definite or (haven't tried to install raid0 yet, for example).

Most reviews of this and other x38 boards suggest that, at this time, x38 doesn't offer much over the P35. Also consider that P35 has been around longer, and is currently the more stable chipset.

In time, I would expect x38 to perform much better than it does currently, but whether this can be achieved simply by an improved bios or whether it will require a revision to the chipset, I can't say.
