With years of maturity and performance tuning, their SLI technology has shown very strong scaling when chaining a pair of GPUs together to tackle the 3D graphics processing workload. We've seen quad-SLI on mid-range GPUs previously with NVIDIA's GeForce 7950 GX2 but what about three GeForce 8800 Ultra cards strapped in under the hood? Green-friendly, eco-minded, tree-huggers or those of you with weak constitutions for that matter; look away. This might not be for you. NVIDIA's 3-Way SLI has been announced today and this performance showcase at HotHardware shows you exactly what it can and can't do for you."
