Will 4x GTX 480 be worth it for 3D Surround?
 
So just got my third standard clocked eVGA GTX 480 and will be putting together a new build, running a 2x SLI setup now, and I was thnking about the Asus Rampge III Extreme for the motherboard, apprarently you don't need the NF200 anymore, 4x SLI should would with any SLI motherboard with that has 4 PCIE slots. Guess I could always get an eVGA Classified board if needed but would prefer the Rampage III.

The intenet is to run a triple head 1920x1080 setup. I've got the power curcuit to handle it so no problem, have a window AC to deal with the heat, plan on using a Mountain Mod case and don't plan of using water cooling. Noise will be not a problem because of how my office is steup.

Thoughts? Please no BS, serious and helpful comments only, thanks!:afro2:

Rampage 3 will be a very good board. Unlike the 4-way Classified it will fit in most computer cases. I would wait on buying the forth 480 though. ATM there isn't much performance increase going from 2 to cards to 3, let alone 4 cards in SLI. That should change though when the drivers mature a bit.

You certainly will need a lot of graphics power to run 3 monitors in 3D, that's for sure.

I would think he would need 2 PSU's if he was going to run 4-way GTX480's. He could get away with just one if he was going to stick to 3-way SLI though. jAkUp was playing around with 3 480's running a Corsair 1,000 watt.

Can't comment on your mobo but if I remember correctly i7 / X58 does only support 40 PCIe lanes / links so if you are running more than 2 graphics cards you will need to set them up as 16 / 8 / 8 or, with quad SLI, 8 / 8 / 8 / 8, and I'm not sure I would want to do that with a bunch of GTX 480.

Ok, back in 2003 I set up a 3-wall CAVE with 6 pcs each consisting of a P4 3GHz, 1GB RAM and a FX5900 128 MB. Each FX5900 was connected to a 1280x1024 beamer, 3 pcs rendering for the right eye and the other 3 for the left. We used passive polarisation filters in front of the beamers and cheap passive glasses instead of electronic shutter glasses.

Your current setup with an i7-980X (eek!), 6GB RAM and 2 GTX 480 has more power than my setup had and should be sufficient to drive 3 displays (as soon as drivers are available).
My understanding of http://www.nvidia.com/object/3DV_Sys...echnology.html is that drivers should be available any day now :)

My CAVE project has been discontinued (restructuring :() and I will have to get a Nvidia 3D vision kit myself to get going with 3D again.

...oh, and you might start beginning to think about a new psu too (3x GTX 480 in *one* box and an oc'ed 980X and the rest of your system might bring a Galaxy 1000 to its limits :)).
...and I would start thinking about temperatures in the box too.

.

The Rampage 3 has 4 16x PCI-e lanes that can run at x16; x16/x16; x16,x8,x8 and x8/x8/x8/x8

No, not even remotely worth it.

First off you'd have to ditch your two current monitors and buy three new ones at $400 a pop. Second, Quad-SLi isn't really showing all that much in benchmarks, maybe future drivers will help but I'd wait and see before I dropped all that money on two more cards, three monitors, and another power supply.

Thanks guys. I think the Ultra X4 1600 will have plenty of power for it. I guess I just wanted to know if I should proceed with getting the Rampage III over the Classified. I'm going to see how 3 480s work and how well multi-monitor works before I'd get a 4th 480anyway , just wanted to be in a position to go that route if I so choose.

Are you in the US? I don't think a standard US 120V outlet can allow a 1600W power supply to completely utilize its power. You'll either have to use two smaller PSUs or get your outlet upgraded. Also, as far as I know, 3D Vision drivers are still in beta for Tri-SLI and Quad-SLI setups, so you might be relegated to playing your triple monitor setup in 2D until NVIDIA releases better 3D Vision drivers for Tri and Quad SLI.

Wow thinking about this is just crazy, maybe for folding or rendering but anything other than that would be way over the top.

FYI Rampage III does not come with a 4 way sli bridge and Asus website does not mention 4 way sli in the specs

http://www.asus.com/product.aspx?P_I...ksC&templete=2

Unlike CrossfireX where you can connect three 2 way connectors,you need a 4 way sli bridge to make 4 way sli work.

They are not sold seperately so only option is to buy/borrow one from an evga 4 way sli owner.(if you can find someone sells)

I was considering a similar setup to yours and bought an EVGA 4 way sli last week because of the 4 way sli bridge.

Hope this helps:)

A standard 15 amp line in the US can handle 1440 watts @ load and I have a separate circuit and can add another if needed. This rig on is on 15 amp circuit by itself withnothing else will be fine.
