You chose a 6 module RAM set in hexa-channel.
The Asus Sabertooth only has 4 RAM slots, and supports dual channel.
24GB is overkill to the extreme for most casual users/gamers.
8GB G.Skill Ripjaws X 1600MHz CAS8
$100 less, should suit your needs and leave 2 slots open for future additions if you find you need them.
If this is solely for gaming/general use, I'd drop down to an i5 2500k and save another $100, features on the 2600k don't benefit gamers.
$200 saved put toward the video card will cover the difference between the GTX570 and GTX580.
(If you can trim 200 more you can snaggle a GTX590)
