1. The motherboard has a 4 VRM design so overclocking on it is not optimal.
2. Do you need two small SSDs? Why? You still need to keep programs installed on the SSD that you have the OS in.
3. Corsair CX line is NOT for performance builds. They are built for low-end builds and have poor capacitors. Definitely not recommended for your high-end gaming build, especially on overclocking.
