which one would be the faster.
4x 4890 in crossfire or 3x gtx 285 in sli
Both would be beaten by just 3x 4890 or 2x 285.
How do you make that out? Additional overhead fvrom dealing with the multi-card setups? Surely 4x 4890 is faster than 3 x 4890 (although I know the scaling drops off so you'd probably only get 10% - 20% increase...)
I'm curious as to how *anyone* could have enough money to even consider those set ups! (quite apart from having a board with 4 PCie x16 slots with enough spacing to fit 4 dualslot graphics cards in...)
If 4 x 4890 is slower then 3 x 4890, then 2 x 4870x2 or 2 x GTX295 wouldn't be very good setups surely?
I would have thought that an i7 rig would handle them fine, although good luck finding someone with the kit to try it![]()

I would get two GTX295 / HD4870X2 to be honest, but to answer the question I reckon the GTX285 tri sli would win, the 4th HD4890 may offer -50 to 20% performance boost, and the 3rd GTX285 will probably offer -15 to 30% performance boost, and more gpu's you have the less they scale.
But there will be a solution. Search google for "Lucid Hydra 100", linear scaling with up to 10 gpu's possible
500fps for crysis, anyone?
It should be featured on the Intel Smackover 2 X58 board which comes out soon, fingers crossed.
I think such large SLI/Crossfires is a waste of both money and power,it must cost a fortune..the way the graphics card market moves its about as useful as throwing you money into the American economy.My opinion though would be the tri GTX 285.
Hardware reviewers and people who have company resources to build killer systems. We've seen a 24 SSD RAID-0, we *have* seen Tri/Quad GPU reviewed in the past, so I wouldn't be surprised if someone eventually crossfires the two 4890x2 (I'd expect those to be eventually made to replace the 4870x2).
Could the average enthusiast afford it? No, but I am sure many can - it's still cheaper than a sport car by an order of magnitude.. or two. Would they? Probably very few, it's certainly hard to objectively justify such expense, but more power to them if they do.
Personally I would expect diminishing returns with each GPU added, but I don't think that performance will be decreased at that point yet (assuming the game supports those number of GPUs).

Based on the results there between 4-way 4870 vs 3-way GTX280, I am going to go with nVidia. It should be noted that CrossFire seem to not scale too well at time, and nVidia did tank pretty badly in at least one test. nVidia 3-way still got the highest average though.

thanks guys so the gtx 285 tri sli is still king.

Hmm, maybe this summer I will see what tri sli is all about (when 40nm gpu's arrive anyway - use less power and more performance)
It isn't worth it unless you have a lucid hydra 100

If in doubt, you can always get two of them. We have multi-CPU, multi-GPU, tri-channel memory, RAID, so it is only appropriate that you through multi-PSU in the mix![]()
