sata 3 internal controller

[spyroszarzonis]

Hi, my motherboard (gigabyte p35-ds4) has only sata 2 ports. I have a Samsung 840 Pro 256GB SSD which right now is limited to sata 2 speeds(about 250mb/s write and 270mb/s read). Is it possible to buy an internal pci-e controller with sata 3 ports still be able to install OS X. I know i can install a sata 3 controller with pci-e but what i really want is if there is any pci-e internal sata 3 controller that is compatible with OS X. I really want your advice here in order to achieve max speeds of my SSD.
