My friend wants to build a new pc. A gaming pc that is. Budget = up to 1.7k$ The cheaper the better. Games he wants to be able to run games such as BF3, HoN, Skyrim, WoW, dota 2, and future dx11 games to come. Things he doesn't need: Mouse + Headset + keyboard. So my dear friends what's the cheapest way to do this?
