i7-3770K on ASRock H61M-DGS R2.0 motherboard

Solution
H61 Chipset is designed for the bottom end of Sandy Bridge CPU builds. It lacks the following features;

Native USB 3.0 ports
Native SATA III ports
RAID

They also have only two memory slots and a lower number of PCI-E Lanes and less USB 2.0 ports than other LGA 1155 socket Chipset motherboards. The i7-3770K would be the most powerful processor, but "k" model processors with unlocked multiplier will have no ability to overclock on that motherboard.

H61 is only recommended for users that can do without those features.
