HIS HD7970 Crossfire & Eyefinity Review

Test Setup

Our new LGA2011 bench rig gets its third outing of the day, and the combination of the black and red cards on the black and red Rampage IV certainly looks the part.

Overclocking

With Crossfire and Eyefinity on test we have two areas in which our overclock can be forced to be reduced, and so it proves. Rather than the high overclock we saw on the single PowerColor, our Crossfire setup tops out at 1050MHz. Still a good increase, but certainly nothing like the cards are capable of.
