Half-Life 2

Half-Life 2 also seems indifferent to the number of PCI Express lanes the graphics cards are connected across. The game is so undemanding that the owner of two GeForce 7800 GTX can enjoy an unprecedented-quality 16x-antialised picture in it.

It’s all roughly the same on the d3_c17_02 map – the ASUS A8N32-SLI Deluxe is even a little behind the A8N-SLI Premium. So the standard SLI configuration, PCI Express x8 + x8, certainly provides enough bandwidth for current applications. But maybe the PCI Express x16 + x16 formula can give us a performance gain in some other game?
