Oh good, I see that motherboard does indeed have Hybrid Crossfire support (meaning you can crossfire your integrated card with a regular card). Once you get the motherboard, give AMD a call and ask them which regular cards are supported for Hybrid Crossfire and when the 4000 series will be available for this, so that you can make adequate purchasing decisions in the future for that.
You could have done without the extra gig of RAM, but oh well, also those Creative speakers are kind of dinky, but remember I am an extreme audiophile who spends huge amounts on speakers and equipment, so I am not a good person to take opinions from on that.
How much did it run altogether in NZ$?
