Need quad sli

[Deleted member 362816]

I am being paid by the school i go to to encode and decode video my 1 gtx 580 is dogging in this i need to go quad sli needs to be dual gpus cards are 2 gtx 9800 gx2s going to out preform a gtx 580 in this or not?

 

[plznote]

No a GTX 580 will kill dual-9800GX2's, quad-scaling is horrifically bad. A 9800GX2 performs about GTX 460 768MB. Dual perform about 6870.

crap ok heres the deal i am going to be running my old rig with this.

so i need a motherboard with am3 and 4-5 pcie slots running x8

what ati cards can quad sli and outperform a 580 in this cheap

There option to run two 4870x2s but that will be is hot as a bakery and they computer needs to run 24/7

Wont a 4870x2 x2 or 2x gtx 295s decode better then 1 gtx 580 and i really dont want to leave my main computer on all night my sata 3 ports are allready taking a dumb damn Intel!

You could quad-fire 5770's.

Will adding additional GPUs even increase encoding/decoding performance. I mean I know that if you're using CUDA then if your GPUs are in SLI then CUDA only "sees" one GPU, I don't know about ATI, though.

The 590 dual GPU cards are supposed to break before the end of February. Tw0 of those would give you quad SLI ... I'd expect to spend $1400 for them tho.

Tri and quad Crossfire has been a frustrating experience for many due to driver issues.

So let's round things up, personally we always say stick to one or maybe two high-end cards as there is so much less driver fuzz to worry about. It's like this with ATI, once you pass 2 GPUs you'll often find yourself compromising a lot with new game titles versus multi-GPU support

CUDA plug in ?

Using Premier, see this:

Since you don't have those cards .....you might want to "unlock" CS5 to use CUDA following the "hack" here:
