Please Review My Build

At the Moment, I suggest waiting. A lot of the things you want to buy are sold out. And also prices are a bit high at the moment. Ram is cheap and so are the CPUs and MB's. However, the cheaper PSUs are sold out, HDD's are way expensive.

But please fill this out:

For performance and reliability I'd suggest a Gigabyte AM3+ socketed mobo as it will run your X4 955 and the BD based Zambezi and possibly the Piledriver based CPUs. You may be able to get 1600 MHz. RAM for the same price as 1333 MHz. RAM with current prices, though it won't make much performance difference.

As far as PSUs go you can determine exactly what you need for power in both watts and 12v rail amps. for your current and future build and find objective test reviews of the PSUs to know which are reliable, at the link below. Then there is no guessing or surprises.
