All your links are broken. Anyway, do you know if you have a Microcenter near where you live? They are really cheap, and an i5+mobo is $205. You could even get a Phenom II x4 and a free mobo for $90. Just as good as the i3, and cheaper. Anyway, get 4GB of RAM, and get a 560 SE. 560 SE has pretty decent performance for the price. $130 for the 560 SE.
