There both flashed to 6970's
I am not overclocking yet as I wish to get them cooler properly before I do so, so technically yes 890mhz (Asus Bios) but no not beyond that.
Considering just going with water cooling and using the money for that instead of the new motherboard as I will be able to reuse the setup. The MB is an awesome piece of work other then its craptastic card spacing.
Any good 16X 4X 16x motherboards for under 200$?
When the cards are installed individually they run cool and quiet, the samich effect is killing the rig.
