Huh. Haven't thought about it. I guess since my steam directory is on my HDD, that's where it's installed to? I didn't think that would make a difference though.
Might be worth checking, because really your CPU meets the min, and your GPU should be fine. Maybe try installing it on your SSD.
If you check the system req's, they seem pretty certain they want high speed storage:
Additional Notes: SSD Or Cache-Assisted HDD REQUIRED, Windows Virtual Memory MUST be enabled (16gb recommended)
At least if you need to upgrade something, getting a 1TB SSD is the cheapest solution, and really, a good thing to pick up before NAND jumps in price later this year.
