A single 9800 GX2 on its own is a formidable graphics card, but users should be warned that investing in another card won’t blow the doors off a system. In fact, we may characterize Quad SLI with two 9800 GX2s as a comparable and cheaper alternative to an expensive 3-way SLI configuration – one that will save you both some space inside your system and some money in your wallet. Quad SLI with 9800 GX2s is still in its infancy, so we expect that Nvidia will deliver improvements to this configuration as time goes on. But if it’s vastly superior performance gamers are looking for, then they’re advised to wait for the forthcoming release of Nvidia’s GTX 280 model.
