Two GPUs are great, but are three that much better? When it comes to multi-card scaling, can AMD finally beat Nvidia? Who really needs this much performance? We loaded a super-fast system in single-, dual-, and triple-GPU configurations to find out.
The battle for GPU supremacy is a bit of a waiting game. The recent launch of AMD's Radeon HD 6990 (AMD Radeon HD 6990 4 GB Review: Antilles Makes [Too Much] Noise) and upcoming introduction of Nvidia's GeForce GTX 590 help demonstrate.
Roughly every six moths, two companies with similarly-capable products wait to see what the other one will showcase, hoping to trump that introduction a few days later by tweaking the clocks, power, and configuration of their own product. Both firms use these delays to build anticipation among followers. Though, as that very same 6990 story showed us, being a "fan" of either company is just silly. Why make excuses for one design team's poor execution and then slam the competition for the very same thing?
