I wouldn't bother with the 2600k...the extra cores don't make a huge difference in my opinion...it's not like cutting off a minute or two to finish encoding anything is worth $100.
You can save $10 (well, $18 with shipping) if you go with this motherboard which is very similar and even a little better for the value:
Newegg.com - MSI P67A-GD65 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
If you wanted to cut the costs a little more and you aren't planning on getting a second 570 for SLI in the near future you could get a 750w psu or even a 650w psu being that EVGA's 570 only needs
Newegg.com - CORSAIR Enthusiast Series CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
Newegg.com - CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply
Minimum 550W or greater system power supply (with a minimum 12V current rating of 38A)
These are both from corsair. I've read some good and some bad things about the newest TX series, so I don't know if you'll want that or not, but it's still an option. That overall should save you around $40. You can use the extra $60 for a better looking case (if that matters to you), a better SSD, or get an optical drive which I noticed was missing...if you aren't using an old one.
