RAM suggestions for 965 C3
 

Hello, I was considering upgrade my RAM. Right now I have 4 sticks of WP160UX4G from Supertalent, that would be 8 GB @ 1600 MHz CL8.
I want to move to 16 GB, but I´m kinda lost between brands and if I should go for 1333 MHz CL7, since most of the models I found at 1600 are CL9. What kind of memory would my CPU benefit most of?

I had OC´d the CPU/NB to take advantage of the 1600 MHz of my current memory.

Can you guys help me out with this?

Edit: I am looking for a low profile memory or without heat sink.

These are my specs:

AMD Phenom II 965 C3 Black Edition,
ASUS Crosshair III Formula
MSI R6950 Twin Frozr III @ 6970
