all built for $1028   what could have been better without spending more money?

350watt is a bit low. You may have to get a better psu. Also, Q6600 + interl motherboard should deliver better performance value. Otherwise good as is.

I have a 635watt psu listed at the bottom.

It's all good then.

I don't know that brand of PSU but make sure it's from a reputable company.  A crappy PSU can take down your rig if blows on you.  PSU is not an area that you want to cut corner, pay more and buy a piece of mind.

Oh wow, you got a socket AM2 motherboard for a Phenom
Is it too late to return it?
You need something that supports HyperTransport of 5200 MHz, such as:

The DFI LanParty should give you about as many overclocking options as you can handle to maximize that Black Edition

 
its ordered, not yet built. whats the problem?

Intel would of been the smart choice.

It may bottleneck the cpu.

I don't see the point in SLi motherboard for that system.  And why spend so much on AMD when a similar Intel would easily outperform it?
 
Could have saved yourself $100 and gotten a G92 8800GTS.
 
Its still a nice system tho, gratz
