Asus has demonstrated a four graphics chips running co-operatively on an SLi-enabled motherboard.

So claims Chinese language website PCPOP, which has pictures of the rig and what it can do when running 3DMark 05.

The Asus system comprises the company's Nvidia nForc 4 SLi 16x-based A8N32-SLI Deluxe mainboard and a pair of its two-GPU EN7800GT graphics cards, both mounted with twin GeForce 7800 GT chips, each with 256MB of GDDR 3 SDRAM.

Unfortunately, while the site provides screenshots of the test renderings, along with Windows grabs showing the GPU configuration, it doesn't provide 3DMark scores for the system.

The other question is whether Nvidia will enable four-way SLi in its drivers. It's not clear whether the Asus set-up uses off-the-shelf drivers, an as-yet-unreleased beta driver, or code of its own. Certainly, the system is claimed to have been seen inside Asus' R&D lab. ®
