New Builds - Hardware Canucks
Posting there would be a better place to get some help with this.
Anyways, your build will "work" but there are a few things worth considering...
You're planning to build a BD based machine, but we have no way of knowing how well BD will be. I'm assuming you're an AMD fan, but the prelminary reviews for BD suggest that it's worse than a comparable Sandy Bridge machine. If you're going to be spending on a top of the line machine, why not go for something which will give you the best performance period?
Also, with a machine like that, you should really consider getting an SSD. The Crucial M4 is a good one.
