Yesterday we published our comprehensive review of the new Nividia GeForce GTX Titan graphics card, but it lacked one important item. How do two, three and four Titans perform together? We tested all SLI combinations, including 5760x1080 and frametime tests, and compared the results to GeForce GTX 690 Quad-SLI.
Nvidia itself only mentions SLI and 3-way SLI, and indicated that 4-way SLI would not be possible with the GTX Titan. However, the Nvidia-sponsored overclocker Kingpin has already posted 3DMark scores with four Titan cards on HWbot.org. We of course had to try our own 4-way SLI configuration, and we're happy to report that it's definitely possible.
And despite the rather steep pricetag of $1,000, Nvidia is aiming this graphics card at the type of gamers who would buy two or three of these. The similarly priced dual-GPU GeForce GTX 690 performs about the same as the GTX Titan, but is louder, uses more power and is limited to SLI (so not three or four cards). Since you can combine three or even four Titans, you're able to get more performance out of the Titans than you can with two GTX 690s.
You obviously don't need this much graphical power for most things, but we've come up with a few extreme scenarios where a second, third or even fourth Titan can be very useful. (Read: Crysis 3!)
