Get the P8Z77-V (not Pro).
The Sabertooth doesn't give you any real benefits over the P8Z77, Z77 is already made for OC'ing. Furthermore, the only difference between Pro and non-Pro P8Z77 is 2 extra onboard USB3.0 connectors on the Pro.
Save the money and buy a CPU cooler, which you will need for the 3570K.
I'd go with Cooler Master Hyper 212 Evo, popular and inexpensive.
The savings from Motherboard will pay for the cooler and a bump up to this video card...http://www.newegg.com/Product/Product.aspx?Item=N82E16814130812
Basically the same but 3GB RAM vs 2GB (only $10 difference with rebate)
