Idk about Canada, but you can build a pc for cheap. First you will want the essentials, like motherboard and processor. And don't forget the HDD. If it's a gaming pc, you'll want a decent graphics card. I would reccommend 512mb-1gb. You will then want to get RAM. If you are 64bit, get 4gb. That should be enough to play the latest games. And don't forget a good cooler. I would recommend shopping around, getting the best you can buy, in your price range of course. Now, you will want a sound card, to blast your ears out. Then a good case, and the rest of the stuff is self-explanatory...If you are a computer nerd like me. Remember, google is your friend.
