I plan to buy a Phenom II X3 7200 CPU with a Gigabyte GA-MA770T-UD3P
motherboard. Of course, this is not an i7 board and it offers dual
channel instead of triple channel memory, even if memory is DDR3.

So, is it worth paying more for lower CAS latency.

Kingston KVR 1333 DDR3 with CAS 9 would cost $85 (CAN), OCZ Reaper
1333 DDR3 with CAS 6 would be $125.

Is the OCZ worth the difference on this board?

Oops! On its site, OCZ says:

"Important Note: Due to the size and orientation of the heatsink,
Reaper X memory cannot be installed on motherboards that require the
modules to be inserted in sockets side by side."

As far as I know, memory must be paired on dual channel architectures
and the banks are side by side.

What does OCZ mean exactly?
