After my summer job I now have enough money to buy a computer. My budget is $620 because I also have to pay for my car and things like that. Here's the link: http://pcpartpicker.com/p/VFmbyc . I will be pretty far away from the router because my parents are over protective and won't let it leave their room and it has a timer on it so they won't move it anywhere else. Will the wireless adapter work through 3 floors? And do you have any other changes I should make?
