They always have had good advice IMO. You have to read, and try and understand what you're reading, but they are good for giving a number of choices, not just 1. I linked directly to the "Sample Builds" page, but you can go back per page for individual components too.
And since you're in Canada, here's a few places that have good online presence for components:
http://www.memoryexpress.com/
http://www.ncix.com/
http://www.newegg.ca/ - Be really careful here, as their shipping times can be long sometimes as their warehouses are in the USA, but it can be very very worth it.
Obviously you have cards for Amazon and Future Shop so those don't apply to every component, but when spending the extra $100, look into them. Amazon and Future Shop have decent online presences, but with Future shop, have the item name EXACTLY and sometimes their search works. When in doubt, get the RAM there, as it is only really constrained by the type. Their selection of other stuff (cpu/mobo) is likely less than amazon. The other vendors above have everything else though.
Good luck.
