It´s good to write things like this, I guess.
A minute later I found the HP part number:
Hewlett Packard 6PIN TO DUAL-6PIN GRAPHICS ADAPTER
F5J05AA
This let´s you split a 6pin connection to 2x6pin.
--
Similar adapters are available from 3rd party vendors.
I can´t tell how well this would work when using "hot" nVidia 7xx range
cards
but the gt 970 cards are spec´d for needing roughly 150W, drawing around
180W in
actual test scenarios.
--
I´d guess that would allow a stable 2xGPU system (using a HP 1100+W PSU)
but for a 3-4xGPU system, I´d actually revert my suggestion and go
home/custom built.

There is a grain of salt.
Most if not all graphics cards come expecting an additional 2x6pin
power supply,
e.g. 75W from the PCIe slot, plus 75W from each 6pin connection, there are
Quadro cards that are spec´ed for 150W power consumption but most
gaming cards will excess that 150 W drain limit.
You´d need at least 4 6pin connections for 2 gaming cards.
The HP Z8++ series may present problems because of the way the PSU
provides
these 6 pin connections in a vendor specific cable kit.
There are several cable kits available but I haven´t found a 4x6pin
kit sofar.
This could be a dissapointment for anyone looking into get such a
plattform.
Of course, there is a chance I missed something from the datasheets
and spare parts
listings, as well as a chance the HPZ840 doesn´t have such a limitation.
Worth mentioning anyway.

Worthwhile noting that Octane works with the GTX 9XX cards very well.
It also has a really good Network GPU support. Which means you dont
need to cram 4 cards into one machine. If you dont know what you are
doing the machine can go *Poof* very easily.

Hi,
I would also like to recommend a nvidia gtx 9xx card, the available cards
(970&980) have a lower power consumption compared to a 7xx series card.
Aside from that, I would like to point out nvidia CUDA support, which
might
help in a couple of programs, be it redshift or 3d coat or the latest
nvidia games
related tools (fluids, cloth, physics, etc for Maya).
If you have to invest now, e.g. immediately, I´d suggest a 970 4GB
card and
downloading a redshift demo to see if it would benefit your workflow.
If you can wait a bit longer, I´d suggest waiting for a successor to
the 780ti or
Titan (Black) nvidia cards, expected early next year, mostly because
of the
more RAM expected to come with these cards, which would give you more
headroom for heavy scene handling (e.g. shitloads geometry and
raytracing).
There is a lot of new stuff coming early next year, including Houdini
and Nuke
versions more accessible due to licensing changes/options.
In general, I would split my money between system RAM, ssd and
graphics unit,
expecting to work happy with a 128-256GB system OS partition, 64GB
ish RAM,
and a gt(x) 9xx ish card with at least 4GB VRAM (6-8GB prefered).
Making sure that your system has a 800+ Watts PSU will help stability.
>From there, finding redshift attractive, you could always add
another card to
your system, devoting it to getting more out of a single render
license or even
go fully committed and swap your mainboard to a 4x16PCIe version, adding
even more cards.
This implies a tower workstation case and enjoying building your
hardware.
Alternatively, I can recommend looking into refurbished HP Z800/820
or Dell T7500/7600
workstations (on ebay) to get an idea about prices, performance and
extension options.
These plattforms are well enough documented to find a solid, not to
loud machine
that will reliable work 24/7 with a reasonably sized PSU and at least
a 2x16PCIe
graphics option.
There´s caveats with maximum system RAM or the PSU in some of those
refurbished machines
but they tend to be solid machines, well designed.
If all of the above is too much information for you:
Get a gt 970 card. They are the best bang for the buck nvidia´s atm.
Cheers,
tim

Sry but clarification please?

right now 970 is best bang for backs.
they do not heat too much, power consumption is prety low
and they do really good job.
and on top of that Redshift as perfect companion ;)
viewport performance is not that big issue at all between
two cards but being able to utilise GPU rendering with
CUDA is way more higher on the list then couple more FPS
in viewport

I'd stay clear of the ATI/AMD consumer cards if I were
you. From our
experience Soft becomes generally less stable
(crashing a lot more), and
the raycast selection is going haywire sometimes.

the best performance, it really makes more sense to
buy the 970 as they are priced better or 980 if you
have more cash. The Redshift say go with the cards
with the most ram (that would be Titan 6tb, if you got
even more cash), depends on your needs of course.

Either case, now a days, which is the middle ranked
graphic card for softimage? (My budget is around 1k).
