Depends if you want the faster reading times, I personally don't see the point of a SSHD if you're already getting a SSD unless you have the spare cash.
The HDD and SSHD are similarly priced, so that is not an issue.
The SSD is for the OS and my most used programs. It most likely won't fit all the games I want in there, so I was wondering what the best combination was, SSD + HDD or SSD + SSHD.
Edit: SSD for programs, SSHD for games. Is that a good combination, or is the traditional Hard drive better.
