Hey all, can you quickly take a look at the price history graph in this build please: http://ca.pcpartpicker.com/p/pNZZ99

It seems like in early May, seemingly overnight, the price of every component went up by about 50%. Why is that? I can understand some fluctuation but this seems crazy...

Is it an indication that I am grossly overpaying right now?
