Sometimes, less is more. Sadly, that may be the case for Quad SLI.
Nvidia launched its highly anticipated GeForce 9800 GX2 GPU model back in March, and many had high hopes for the technology. Designed to compete with ATI's Radeon HD3870 X2, which put ATI's CrossFire scheme on a single graphics card, Nvidia new product essentially combined two 8800 GTS GPUs on a single card. Therefore, two 9800 GX2 cards would give a system the long awaited and almost mythical power of Quad SLI – but for real this time.
That day has arrived, but the results are once again not what many had expected, including Tom's Hardware. They recently received another monster gaming rig from Falcon Northwest – a Mach V Quad SLI system, to be exact, that came with two Nvidia 9800 GX2 cards. Needless to say, Tom's Hardware were eager to see how a Quad SLI system performed compared to a 3-way SLI scheme, which has produced somewhat mixed results since its debut.
