PowerColor HD7970 Overclocking & Eyefinity Review

Memory Usage

Considering that we have two extra screens running, all with hefty anti-aliasing and the highest possible settings, it’s a genuine surprise to see how little extra VRAM the Eyefinity modes use up. Indeed Far Cry 2 actually uses less of the GDDR5. So for all you people going on about enormous amounts of memory, the mighty Witcher 2 only uses 500MB of the 3GB onboard.
