Is it possible to use 3 or (gasp!) 4 5970s on one system?

Using either P6T7 or Classified 4 way SLI (both have 7 PCI-E 16X slots with TWO NF200s. The board is capable of physically fitting the cards however what about the CF bridge?

Do ATI's drivers support 8-way Crossfire-X?

 

[Udgnim]

think Crossfire just works up to 4 GPUs

This. Last I heard

I watched the video . It says it wasn't crossfire?

Looks like ass on those monitors.

AMD really needs to discuss "ultra thin bezel or no bezel" with the various LCD manufacturers.

I used to wonder why they didn't do this sooner, but that recent RV870 article cleared up a lot for me (re: Eyefinity was an internal secret at AMD almost to product release).

I was chiefly interested in using raw GPU power for encoding processing not video output.

for compute purposes i dont believe you need to run them in "crossfire" mode in order to use every GPU for compute purposes. i know nvidia CUDA doesnt have this limitation, which is why you can have a 4 GPU Tesla cluster when the limit on SLI is 3 GPUs for graphics rendering (+1 for physx but that's just doing CUDA computations). i dont see why ATI would be any different

Ruby, pretty soon you'll need the complete power output from the cruise ship's engines to power your rigs
I demand that you put "Cruise Ship" as your PSU under your rig details

On one hand that video shows how Evefinity can be pretty cool, how you can set up all those monitors to game.

On the other hand, those bezels are so annoying. I'd never want to game on that, it's way too distracting for me personally.

Oh there's plenty of power to spare! Having 230VAC is very nice as a 9A rated cord takes a system to the sky!

Sounds like you would be better off with cuda cards or fermi then!

404, Fermi not found.

Speaking of CUDA I had failures with several 295GTXs. Not sure if they can take 24/7 full GPU load with the stock cooler. We're talking SNAP! Total system shutdown, smell of electronic parts burning! This is probably why there are no dual GPU QuadroFX products.
