Memory Recommendations needed

Hello
I'm in need of memory upgrade.

My specs:
AMD Phenom II 955
ASUS M4A89GTD PRO

Looking for a 8GB kit, I found these two:

Corsair Vengeance and Corsair Dominator


Which one of the two should I get? If there is something better within that budget, let me know

Thanks

Edit: is having 1.65v a bad thing?

Of the two kits I would go w/ the Vengeance series, as they have tighter rated timings w/ lower voltage; 8-8-8-24 and 1.5V compared to the 9-9-9-24 timings and 1.65V of the Dom's.

I just checked the memory compatibility list on ASUS's site and the Vengeance is not on the compatibility list, Am I going to have problems? The Dominator on the other hand is on the list.
