QFT.
if you're looking at newegg, many (but not all) of the reviewers on there leave negative feedback because they're idiots
QFT again.
Thought process: you buy a shiny new board, pay a few hundred bucks, it works great: who do you tell about this? Real studies show that it's about 2-3 people.
You buy a shiny new board in a box, and it's DOA, you can't get it running, it doesn't run correctly: you tell 10-20 people, maybe more. Because you are pissed off.
Another study showed that a very high percentage of returned electronics work fine: the buyers have trouble figuring out how it works, give up after 20 minutes, and return item as "non working".
Keep in mind, every manufacturer will have at least a 1-3% failure rate.
QFT; they could bring that rate down to zero by doing torture testing, "Sigma Six" this and that, and make that $300 motherboard a $900 motherboard because of the cost and time of doing all that testing. Somewhere at Asus and Gigabyte there is a spreadsheet the calculates failure rate/testing costs/warranty costs: it costs them less to have you do that last 1-3% of quality control, and to send you a new motherboard if there is a problem, rather than testing the other 99 boards for a week or two. (Or, as noted in some other threads around here for MSI, sell a board that doesn't work, then ship a replacement board that doesn't work and is all bashed up. Nice.)
Note sure what your budget is, but if you want a powerful reliable video editing machine:

Mac Pro. Not cheap, but, all top shelf components, and with Apple volume discounts, it's cheaper to buy it from them than assembling it yourself. Can run OS X, Linux, FreeBSD, and Windows just fine.
To get a top quality motherboard, consider server boards:

Supermicro: about 170$$:

Some highly reated boards here:

Some highly rated AMD boards:

Combine the above with one of the new Phenom IIs, which AMD did get right (read some of the reviews) and you can get quad core video editing goodness.
Note: one this I like about AMD is that you can use ECC RAM: essentially the same price as regular DDR2, and, justs adds a bit (no pun) more reliability, especially if you are doing long video processing runs.
Anyway, worst case scenario: you get a DOA board: you return it, get a new one. Newegg is very good about returns, or, buy locally, so you can swap out a problem board right away.
