Hello,
One of the best SSD available is the Samsung 830 series. It would work great with the P8Z68 MB.
Maximum PC magazine rates them as "the best of the best" in the SSD area.
Also, the prices of the SSD's have come down tremendously, 35-50% over the past year, and you can get an SSD for less than 1 GB per dollar.
The Samsung, for example, has dropped 47%, and on Amazon is $119 for a 128Gb drive, a $219 for a 256GB drive.
There are other very good ones available, as others may recommend. For now, I'd not consider OCZ, until they get the "stuttering" and random BSOD problems cleared up 100%.
