Overclocking
Remember just how well the reference card scaled beyond its shipping frequencies? The XFX, as used with the Enthusiast BIOS, scales just a bit higher.
Remember, we increased the GPU voltage from 1.09V through to 1.17V, as per the reference card's overclocking methodology.
And there's enough speed to jump clear of a Radeon HD 7970 and, surprisingly, match a twin-GPU GTX 590.
XFX, give us a 1,000MHz/5,750MHz-clocked card out of the gate, please.
