Nvidia 197.55 Drivers Enable 4-way Fermi SLI
 

When the Nvidia GeForce GTX 480 and GTX 470 launched, it only supported SLI with three GPUs. While supplies of the new Fermi-based cards are still scarce, now those who find three cards not enough now have an upgrade path to add-in a fourth card.

Nvidia today released GeForce WHQL drivers version 197.55 that enables 4-way SLI for GTX 480 and GTX 470 cards.
