Now that we have motherboards that offer two PCI-E x16 slots, is it worth getting one, or is it just overkill at the moment? Do today's top graphics cards require that much bandwidth? Maybe, but to test this theory, the folks over at t-break put two 7800GTX up to the challenge. Is it time for an upgrade?
"Today, we take a look at nVidia's nForce4 x16 chipset that offers two PCI-E x16 slots to provide the maximum bandwidth to video cards running in SLI mode. However, is this really needed with the current generation of cards or, like SATA2, its simply an overkill? That's precisely what we'll find out today by using two 7800GTX cards in SLI mode on a standard nForce4 SLI motherboard as well as an nForce4 SLI x16 motherboard. Lets look at the testbed."
