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.
im curious as to which would be fastest out of those though?
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...)Quote:

I would have thought that an i7 rig would handle them fine, although good luck finding someone with the kit to try it :P
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 :P
500fps for crysis, anyone?
It should be featured on the Intel Smackover 2 X58 board which comes out soon, fingers crossed.
Is it even a fair fight? 4 vs 3?Quote:

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).Quote:

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.
I am sure alot of people could afford the top end hardware, and alot of it, but theres no points when a cheaper one suits your needs tbh
:)thanks guys so the gtx 285 tri sli is still king.:rockon2:
so are you going to get a tri SLI or we just wasted a few hours on theoretics?Quote:

It isn't worth it unless you have a lucid hydra 100 :P

what im interested in is, how do you get a powersuply to run those 4 cards in one go?
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 ;)
