SSD OCZ Agility III 120 GB Running Slow after Motherboard and CPU upgrade

Hello, I was running a 120GB OCZ Agility III on another computer. I just upgraded to the Asus Sabertooth Z77 and i5 3570K but reused the SSD and HHD. However, my read/write speeds dropped signigicantly WEI went from 7.9 down to 7.4. CrystalDiskMark went from 250 MB/s read and write down to 200 MB/s read and 100 MB/s write. The difference is noticeable especially when starting my computer. My WD Blactk 1.5 TB storage drive writes at 150 MB/s, shouldn't it be much lower than the SSD?

I am plugged into the Intel Sata III ports and using new Sata III cables. I have tried changing to other Sata III cables and get the same result. I also get the same result on ACHI and IDE Bios settings.

Can anyone help?

1) did you do a fresh install of windows when you moved the drive to the new system?

2) are your drivers up to date?

Yes and Yes, bios too. Its odd. I am considering an RMA but I do not know if it is the SSD or motherboard.

CrystalDiskMark uses highly incompressible data to test Read/Write speeds.

Advertised speeds for OCZ drives are with ATTO & AS-SSD benchmark software.
AS-SSD is similar to CrystalDiskMark in that it also uses highly incompressible data to test Read/Write speeds.

Advertised AS-SSD speeds for your drive are "up to" 195MB/s read and 130MB/s Write.

If you are looking for the advertised 525MB/s Read and 500MB/s Write, then you have to benchmark with ATTO, which uses highly compressible data to test Read/Write speeds.
