Windows 7: Asus P6X58D-E - SATA II SSD or SATA III SSD?

Hey guys sorry if this is in the wrong section, but i'm looking to upgrade from a HDD to SSD. I've been reading online about my board and apparently the marvell 9128 controller sucks speed wise. I was looking at the Corsair Force 3 because of the read/write speeds. Upon doing more digging though it looks like id be better off running a drive on the SATA 2 ports. Would I then be better off getting a SATA 2 SSD for slightly cheaper?

I'm confused on what to do. Any advice would be much appreciated.

Cheers.

See My Specs. Intel SATA II works better for me than Marvel SATA III. All those spec sheets means very little in real world applications. I chose the Intel 510 for three reasons, reliability, reliability, 5 year warranty.

Cheers for the reply mate. I can't really afford to buy a new board yet and I'm unsure if I can get a PCI card that will run the drive to its stated speeds. The intel drives look a little pricey I'm looking to spend about £100-120 on one. I have a £150 budget but I also need a new mouse lol. The corsair drive is £114.99. Can anyone else recommend a drive best suited for my board for that price. Needs to be 120-128GB.

Cheers.
