The concept of Quad-SLI rendering isn't a new one, as nVidia has sold these products as an ultra-specialized premium product for several months now. However, the Quad-SLI implementations we've seen to date used custom nVidia cards which were never mass produced. With the release of the GeForce 7950 GX2 product, everyday gamers now have the opportunity to get their hands on cards which can work in parallel for quad-GPU rendering. Each GeForce 7950 GX2 board is equipped with an SLI connector on the bottom PCB, and two cards can be plugged into a motherboard using an nForce4 SLI X16 or nForce 590 SLI chipset (both offering dual PCI Express x16 lane configurations), connected via an SLI bridge card, and voila! Quad GPU rendering. Yes, ladies and gentlemen, we've officially gone overboard
