@ulysses: They post like that because that's how they're supposed to post according to the guidelines. If they don't, you get an opening post that is a giant brick of text that doesn't tell you anything you need to know. Which means they get crappy advice, or at least it takes a lot longer to get any advice. While you may be bored by the guidelines, I find them helpful as I can glance at the first post and immediately have an idea of what they need.
As for the actual build, have you considered using an AMD CPU? Here's a better gaming build that should be about the same price (prices/links from Newegg.ca):
The board doesn't support Crossfire, so if you want one that does, grab this combo with the X3 and Gigabyte GA-790XTA-UD4 for $51 more. I would look around for some more deals, as I have no idea where the best place to buy parts in Canada is.
- 750W is overkill, 650 seems more appropriate.
- DDR3-1333 is as fast as 1600 in real world apps and often a bit cheaper.
- I'm not that fond of the 922. It's noisy, expensive and the extrra cooling is seldom needed. Certainly not with such a modest CPU and reasonably cool GPU. But that's personal, feel free to take it anyway.
I've heard that the 922 is actually pretty quiet (I don't own one). As for expensive, considering that it's actually bigger than many "full" tower cases, it's extremely cheap. I can't actually think of a high quality case that's as big that's the same price or less. You also need a huge case, as the 5870 is fairly long.
1600 mhz sticks are better than 1333 mhz sticks when you start overclocking. Other than that, they're very similar. Besides, they're often the same price.
