Looks like you're aiming to overclock the Phenom to 3ghz-ish.
 
I don't think you need any advice. You have done your homework. If I may, what are the uses of the pc?

You might wait for the 48xx series to come out. It should be here by the end of the month; I think 480 SPUs will be worth waiting for
 
You might consider a Corsair PSU (750 TX or 620 HX) rather than the ABS Tagan.
 
And I prefer a Razer gaming mouse (just because.).

The only use for this PC is Gaming Vid card will be crossed fire

The motherboard will be:
