Thank you for answers!
But here at Brazil, prices are beyond from this galaxy..
ASRock 990FX Extreme3 R$ 468,00 (U$ 209,0) + shipping cost;
ASUS M5A97 EVO R$ 476,00 (U$ 213,0) + shipping cost;
Gigabyte GA-970A-UD3P R$ 465,00 (U$ 208,0) + shipping cost.
The GA990FX-UD3 here cost R$ 620,00 (U$278,0) + shipping cost. Out of question =\
So, one of these 3 mb cited before is my goal...
