Anything you'd change? Particularly interested if the PSU I chose is going to cut it.
Do you plan on possibly SLI in the future? If so, you need to up your PSU to the 750 watt version. If not, then you will be fine.
I would replace the Gigabyte 670 with the MSI 670 Power Edition.
Can't go wrong with the 3570k, best you can buy right now.
Finally, I would replace the RAM with low-profile stuff like this. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Hope this helps!
