before i crossfire them should i turn the asus card upto same speed as gigabyte?. cheers

One of the cards will automatically raise/lower it's speed to match the other card.

The faster GFX card will step down to the slower in crossfire mode.

Manually overclocking the lesser to match might result in heating problems.

Enjoy the FPS.

Just crossfire the cards and see what happens.As mentioned,one of the cards will change it's clock speeds to match the other card(most of the time,it's the faster card that lower speeds but in few occasions,I've seen the slower card raising it's clock)

Since when AMD synchs? The faster card step down, it doesn't raise.
