According to Wikipedia, social determinants of health are "the economic and social conditions –- and their distribution among the population –- that influence individual and group differences in health status". It probably is not terribly surprising to you if I said people in developed countries have dramatically longer life expectancy than those who live in developing nations, simply because the latter lack even the basic necessities for living, such as clean water and food. But for those who live in developed countries such as Canada and the United States, what determinants do we include when we benchmark these nations against each other? Many researchers propose factors such as income, housing, and employment. While this is nice and agreeable, in my personal opinion, they are all missing one very important aspect. If anyone wants to be healthy, what they truly need is a fast computer that starts every time and never crashes. At the end of the day, let's admit it: We have all screamed and yelled when your computer crashes at just the wrong time, or at the very least, become frustrated at unbearably slow PCs. All these will cost a few years of your life in the long run. So for health related reasons... I think it is time for you to upgrade your desktop, haha. After all, you only live once. To give you a hand, what we have here at APH Networks this morning is a mainstream performance motherboard from Gigabyte. Promising excellent performance, top notch stability, and rock solid reliability that won't break the bank, will the GA-Z77X-UD3H fit the bill? Read on to find out!

Our review unit of the Gigabyte GA-Z77X-UD3H came in a medium sized, corrugated cardboard box from the company's American offices in California, USA. Funny to mention the Golden State, because I have always imagined how nice it would be if I was there when it is a chill forty degrees Celsius below outside in the winter here in Calgary, Alberta. But now that I have my central air conditioner running at a temperature that most Californians would laugh at, what can I say? I would much rather be where I am right now. Chit chat aside, using UPS Saver, the motherboard landed on my doorstep in excellent condition as always. So we cracked open the box, and got straight to work... three months after it arrived. Yep, the infamous APH Networks backlog. Oops.

With a new generation of motherboards is a new retail box design theme. This year, Gigabyte decided to use a clean white background to highlight the GA-Z77X-UD3H. At first glance, I heard myself saying, "Nice!" Traditionally, motherboard manufacturers tend to pack as much information as they possibly could onto the front of the box. Well, I think someone finally realized no one actually reads everything, and when you overwhelm consumers with too much information, they might just end up not reading it at all. With the new design, it is much cleaner. From a consumer's perspective, I am much more interested in seeing what the marketing people want to say about this product. If you just look at the picture above, it shows off two main features: 3D Power and 3D BIOS. This is thematically enhanced by the cube frame prominently displayed. An array of icons and logos at the bottom highlight other features of lesser distinction. Other than that, I don't think you will have a problem finding the make and model of this board, so before we move on, let's take a look at the specifications of the Z77X-UD3H, as obtained from the manufacturer's website:
