Released Models

As mentioned two models are being released at this moment: GeForce GTX 280 and GeForce GTX 260. Below you can see pictures of the reference model for these two cards – as you can see, they have the same external appearance. Both cards require two auxiliary power connectors, with GTX 280 requiring one 6-pin connector and another 8-pin connector and GTX 260 requiring two 6-pin connectors. Both video cards are based on PCI Express 2.0, naturally. So for best performance you must install them on a motherboard supporting PCI Express 2.0. Both of them support three-way SLI.
