PCI-E Sata Controller - SSD Performance?

Recently I was experiencing some stuttering issues in some games when they would run fine for 10-20 seconds then stutter, not too sure what is was or is. I decided to try and move the game (in this case modded, which may be the issue, ETS2) to my SSD. I tried some other games than were stuttering occasionally and all the stutter seems to be gone and loading times seem to also be slightly improved. Since I don't really want to fill up my boot SSD was all my games, I was thinking of buying another SSD to put some of my most played games on there. However the motherboard which I have (MSI Z68S-G43, idea of replacing the motherboard in previous posts with Extreme 4, fell through due to financial problems at the time) only has 2 SATA III ports and my boot SSD is plugged in one and my main storage drive (1TB Blue) which currently holds all my games, documents etc. is plugged in the other which I would still use for some less demanding (which seem to run without stutter) and less played games.

Since I don't really want to go down the route of replacing my current motherboard and processor just to get an extra SATA III port, I was looking at getting a PCI-E SATA Controller. I was wondering what would be the performance gain/loss of using a PCI-E controller rather than a motherboard port, I would plug my boot drive in it and probably my new SSD and do SSD's benefit being plugged in a SATA III port and mechanical hard drives for gaming or could I just get away with plugging the mechanical drive in a SATA II without losing any performance?
