No, no RAID. RAID 0 can increase performance but is risky. RAID 1 is costly but not increase any performance but you are more safer. Just plug the SSD to SATA 1 and HDD to SATA 2. Make SSD bootdrive and Install Windows!
By the look of your configuration, I see that you are very high end!! A GTX 680 SLI? MAN, you can get another 1TB HDD and connect that your SATA port. Make sure you plug it into 6Gbps and go for RAID 0. It can increase performance
