If you intend to buy an INTEL Z68 board, be wary that ISRT the so called Intel Smart Response Technology (ISRT) might not work very well yet. This is probably due to driver issues or some other problems which remains to be resolved.

In fact, this can be confirmed as we received news that a number of reviews out there in the wild did not include test on ISRT. I am not sure why other review sites published their reviews without testing the ISRT function. On the other hand, some other sites are holding on to their review to get it sorted out.

So, you might want to bear this in mind and wait for some these issues to be resolved.
