can 3 Nvidia 9800GX2 SLI Mode play the game CRYSIS at 1920x1200 at 40fps?

nope.

no hexa-SLI drivers.
no nuclear power supplies out yet.

Not to mention that it's not going to EVER be possible to do 3 Way SLI with those do to it having only 1 SLI connector when you need 2 to have 3 Way.
 
That, and Crysis isn't worth $2200 in PSUs and GPUs alone to play. It never will be. It's not even that great a game.

As the first poster said, no drivers, nor any plans to make them.

Plus you'd need a 1200+ watt PSU that'd run $350+.

Plus the cards have a single SLI connector, limiting them to SLI with 2 cards only.

Plus there is no support for GPU scaling beyond 4 GPUs in DX10, due to a 4 frame buffer limit. Since there are 2 GPUs on each 9800GX2, 2 9800GX2s in SLI is the most DX10 can support. Ever. Barring, that is, a total rewrite of how Nvidia handles SLI.

This post brings me back to the 7950GX2 and the main reason it sucked so much bulls when scaling. DX9 only had 3 frame buffer support but the 7950 had 4 frame buffers so that crippled performance since that extra frame buffer just sat there doing squat. I wonder just how much better Quad SLI will fare now that DX10 is in the mix. Kind of interested in seeing how that turns out but not interested enough to spend $1300 on GPU's :p.
 
Both teams seem to be pushing multi GPU alot lately, so hopefully more and more games will support it. Also with vista actually supporting 4 frame buffers quad SLI should come into its own a lot better now. In theory, a good 750w PSU is enough for quad SLI. I plan on picking up a corsair 750TX to run quad. It has 59? amps on a single 12v rail.
 
I want to see something more efficient that scales better than the AFR method currently used. It seems that something as parallel as graphics rendering should scale better with more processing power. I guess its just hard to do it efficiently for real-time rendering.

Wish I knew more about the theory behind it so I could comment more intelligently on it.
 
But most basic of all (as has been said) is the physical level: if you cannot physically connect three of them together, the rest of it is moot. Only 1 SLI connection on the 9800gx2.
