Help on deciding which 2 components to buy!?

[tinhtoiom123]

So here is my current build: http://pcpartpicker.com/p/wkgssY
(Note that the Video Card isn't listed because I couldn't find it, but it's basically a Radeon HD 6870)

So, I want to upgrade my Video Card, Power Supply, and CPU to these:

Video Card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150686
Power Supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182073
CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819116504

The issue is, I only have enough to buyeither the video card and the power supply or the CPU and the poer supply. Which pair would be best?
