Sapphire Radeon 7970 Quad-CrossFire First Look Performance

When we originally published our 7970 content on January 9th 2011 it wasn't possible to run Quad CrossFire with the 7970 and MSI's new X79 Big Bang XPower 2 motherboard. The configuration simply wasn't enabled. That changed overnight with a new BIOS from MSI and new driver from AMD (dated 5th January) which allowed us to test 4x7970 in CrossFire. @ HardwareHeaven
