Gtx 285 4 way sli vs HD 5870 4 way crossfirex

[SLI-FPS]

hey everybody i am gonna build a gaming rig and i don't know what is better

4 WAY SLI GTX285 or HD 5870 4 WAY CROSSFIREX

the whole of the rig:

asus p6t7 ws supercomputer

1tb samsung spinpiont 1tb

6gb corsair dominator

cooler master atcs 840 black

swiftech h20-220 apex ultima

windows 7 ultimate

corsair 1000HX

and i wanna know is the power supply will be good?

You need a bigger PSU. There is no single CPU out to date that can harness the power of 4 of the GPU´s mentioned. They will perform the same because of CPU limitation.

I don't think you're going to be able to 4 way those. 4 way sli only works between 2 cards with 2 gpus on them like 295s. However in most cases 3 285s will beat 2 295s.

I suppose you could 3 way some 285s and then use the last card for physx.

I think Crossfire works in 4 way, but is slower than 2 way unless you are using a 2560x1600 display. Which I'm betting you are.

If you want a cool gaming rig wait until Fermi comes out(January or February), if it's good get two of 380s, the new 24" acer 3d display(set to come out about the same time), and some 3d vision glasses. If Fermi is bad go with the ATI solution.

what power supply do you recomend?-

omg magic pants, that's one amazing link you have there XD

 

[wh3resmycar]

the corsair hx1000 can power a rig like that.

 

[obsidian86]

you do realise 4 way sli has 3 6 pin connecters per card an the crossfire only has 2 6 pin connectors per card the hx will power the ati set but you'll need more for the sli set like the silverstone 1500 watts or ultra 1600

 

[seerwan]

bit of a strange question, and possibly off-topic, but if the case is left open, can some of the graphics cards use a different powers supply?...

 

[obsidian86]

yes big cases can house 2 power supplies, the extreme overclockers use 2000watts generally 1000watts to power the graphics cards 1000 watts for everything else

 

[wh3resmycar]

that will depend on the case as you'll only have 1 power button.

Given the poor scaling of 4x Xfire or SLI, I might suggest going 3x Xfire with a dedicated PhysX card by nVidia. You still have monster power, you have DirectX 11 and PhysX. You don't even need to have a board that can do both SLI and Xfire, because the nVidia card is not being used in either formation.

i tink 5970 crossfire would perform better and cost less

 

[SLI-FPS]

all of you men you leaved the center of the question i wanna know what is better

4 WAY SLI GTX 285 or 4 WAY CROSSFIREX HD 5870.

4 WAY SLI GTX 285 or 4 WAY CROSSFIREX HD 5870.

If you just want to know which gets higher benchmark scores, and are not serious about building anything, I'll leave you with this info:

When I benchmarked my machine with 3dmark vantage and 3dmark06, both showed the fasted computer benchmarked, and both had 3x 5870's in crossfire.

 

[obsidian86]

4 way crossfire is better

 

[Milos-stancene]

2xFermi-Tesla

 

[whemian]

4 way 5870 would be %50 faster then 4way sli

 

[Milos-stancene]

Wait a BIT ....

 

[SLI-FPS]

ok i will wait and not order the pc now i will wait for the gtx 300 and the core i9 and any know the case that support 2 power supplys?

 

[jennyh]

So you're waiting 6 months on fermi and the core i9?

 

[SLI-FPS]

man the sayed the first quarter of 2010 = first 4 months.
