Hello all, im all new here!
Right now im running my Daz studio on a Imac 2014, but when i come to the render part, it takes for ever! it is so sad to see and wait for...
Im only doing portraits with no background, only the face/body and some simple lights..
i have in mind to build a computer only for the render part, but i dont know what to looking for.. i can see having a good graphic card is nessesary.
My budget is around 1000-2000$
And maybe i could use some help with the render settings too :D

let's see, If I were you ai would buy rtx3090 24gb for 1500$ and then spend the rest of 500$ on the remaining stuff.
I would take some used Xeon workstation because the motherboard absolutely must have 8 memory slots
Xeon is pretty much equivalent to modern ryzen in terms of performance and considering its price it is easy to fit into less than 500$ budget with 64gb ram and 12 core cpu
if you want to spend less than 2000$ you should buy 1080 ti used GPU which is about 500$ so you can fit it into a 1000$ budget

I recently bought a new rendering PC, perhaps my thread is of use to you: https://www.daz3d.com/forums/discussion/459621/help-this-n00b-buy-a-pc
Why bother with building your own though? That's usually a lot more expensive than just getting a pre-made or pre-assembled computer (though I suppose it does depend on where you live) but.. not to mention all the extra hassle. I'd just get a premade setup while making sure that it has a high end NVidia graphics card (iRay is simply too good to give up on IMO) and of course plenty of memory.
Everything else doesn't really matter all that much, you won't get amazing noticeable performance differences within that price category.
Those cards are running around $2,500-$3,000(rtx3090 24gb) now.IF you can actually find one to buy.
The prebuilt off the shelf computers are probably going to be the only sane way to get a high end nvidia card at the moment.
I'm not going to spend $3,000 just on a GPU.I'll wait until they are closer to the MSRP before I bother with it.
besides, if your render dosen't fit on the cards memory, it will drop to CPU anyway.That $3,000 GPU may just get to sit and watch as the CPU does all the work.
Good news it that if you play games at all you'll have a card that can run any of them.Except for cyberpunk 2077.That game is a hot mess.
There is no way that your render of pretty much any complexity will not fit in 24GB video card. This is just practically impossible.
even 11GB 1080 is pretty adequate for most situations
This is a rather simple scene.
All loaded with defaults with no changes.
Collective3D's Neighborhood Xpack 2
V8.1
Lori Hair
Cherry Blossom top for G8
Shorts are from FG T-Shirt and Shorts for G8F
Lighting is just the default Sun-Sky only set to 1:00pm
Task manager shows 30+GB in use.
Are you sure this will fit on 11GB or 24GB card?
If I add gendragon3ds' grass to replace that flat painted on yard
maybe add another character so Vicky has someone to walk with
add an hdri so I can have some atmospheric clouds in the sky
Add another home in background behind the fence so it looks more like a real neighboorhood...
that's all goiong to add up, but it will look alot nicer.
Last time I did have all of that in a scene it weighed in around 76GB while rendering.
My 6GB RTX 2060 was of little use.
Here's what I'm getting at.
If you choose to build;build your computer with the most modern parts you can with the GPU you want being a concern while planning.
Currently that means a CPU, motherboard, and power supply that will support PCIe 4 cards.
Next year we may be seeing the first of the PCIe 5 hardware, but that I'm not certain of.
Once you have a base system with an adequate amount of system ram for the things you'd like to do that can't be done on a GPU, you can then buy your 24GB (or whatever is available when you make your purchase) card when the prices are more favorable.But right now GPU cards are simply a bad buy unless you can get a prebuilt system that has the high end card you want pre-installed for a price you are willing to pay.
I went with this plan when I built my rig. I got the 6GB RTX 2060 for ~$400 to "upgrade" my 8GB RX 580 AMD card.Still not sure it was an upgrade but it looks way cooler with the RGB lights.
Here's my parts list.I'm very happy with the results.Once the Ryzen 9 5900X and RTX 3090's become more available at better prices I can upgrade with relative ease.

I reused the old SSDs
Yes, there are things you can do other than load, pose,place,render to make a project fit on a GPU cards ram.I normally don't fuss with that.I like the freedom of being able to "load and go". So I went with 128GB of system ram and the 6GB GPU.
I'm defnitely not an expert but I feel it's overkill to recommend a 24GB card to someone who wants to only make portraits without backgrounds.
Scratching my head over being able to render just about anything with my RTX 2070 Super that has just 8GB:s of VRAM, but maybe I accidentally got some top secret development version that has triple the amount without telling that even to the OS
Agreed. I have a "meager" RTX 2060 which has a 6Gb framebuffer and I've never had issues with rendering complex iRay sceneries. GPU power is definitely nice to have, but it's hardly a necessity which you can't do without.
Your 6Gb is quite far away from 24BG.
that Collective3D's Neighborhood Xpack 2 is huge memory hog because it contains lots of details that are not necessary and to save memory you hsoud turn or unused geometry inside of the house leaving only what is necessary. although on my system it only consumes 1.7GB of system ram
But even with everything turned on it consumes about 5-6GB on my GPU, one character with simple clothes is one again 1GB or 2 Gb with some more complex clothes and hair
So even if you decide to drop 2 of those absurd memory hogs without any optimization and 2 characters with pretty complex clothing you will end up with 18GB GPU memory usage you still have enough memory for 2 more characters and some props.
Usually, you will not waste memory so horribly, You turn off unused geometry and use texture optimizer to scale down 4k textures o distant items to 1K or 0.5k what reduces memory usage 4 times
I did use this sscene in one of my renderings and with some optimization, I easily fit it into 8GB with 4 extra characters.
The problem is even made worse with poor UV mapping, and the result can be that the model requires 10-15 times more memory than what would be required for exactly the same level of quality.
I had hard time understanding why a model from the same source was straining my computer to it's knees, until I started to look a little deeper. Unfortunately the main problem can not be fixed by any of the optimizers or even lowering the resolution or color depts of the textures and abundance of maps.
> i have in mind to build a computer only for the render part
That is a mistake IMO. For me (hobbyist) the graphics performance while working on a scene is *more* important that the render time. I can always render overnight or during breaks, but semi-instant preview of lighting and colors requires a capable GPU.
I'm cheap, so I'd consider a used PC with a fresh graphics card (had an i7 from 2012 with 32GB RAM, that was completely fine for DAZ)
For the GPU, the old motor sport saying applies - speed costs money, how fast do you want to go?
I looked around on eBay and noticed that tesla m40 cards are reasonably priced at 120$ with free US shipping (although only 12gb versions.) I just bought one to put it in parallel to my 1080.
this may be quite a good option for those who want to go ultra-cheap like me. as m40 is about the same performance as 1080 with 12gb memory.
in essence, it is gtx980 without video output and probably reasonably low power consumption
Just stay away from K series and anything else than M40
If you live in the US you probably could buy a pretty good rendering PC for less than 700$ getting 24 gb m40 would be comparable with rtx3090 in terms of memory size even if rendering would be much slower.
I think that's is not quite right, because you need to rerender the same picture quite a few times before it gets right so that's why you need good rendering speed. and preview can be done even on cpu rendering.
simple scenes work reasonably well even on low-end computers I was using PC with just 8 gb ddr2 ram 3.5ghz CPU and it was working pretty well although today, my 48Gb system is struggling sometimes.
If anyone can tell me which SATA 3GBPS SSD could be be great under $150, I am looking at these Solid State Drive SATA 3Gbps Options. And also tell me which brand could be more durable, as I do not change pcs every year, it would be great if my upgrades last several years with a new or refurbished drives.
None of them from that site, they are all way overpriced.
@Onix: I rarely need to re-render my final 8k images, because my GPU can give me a high-quality FullHD preview, where I can catch almost all flaws.
But I was unclear on my main point: when I have a Mac with ok CPU and lousy GPU, and a "Render PC" with an ok CPU and a nice GPU, then I will want to work on the 'Render PC' all the time. It's just so much nicer when you get fast high quality previews. (and you don't have all the trouble with syncing data on two machines).
@johnelton91: these days, maxing out a SATA connection is trivial, every manufacturer knows how to do that. SATA is on the way out, NVME is the up to date standard for SSDs. If your board supports it, that's the way to go (if not, there are PCie cards to retrofit). Modern drives are 10x faster than SATA, but frankly, it's deep into "diminishing returns" territory. Most software doesn't know what to do with that much data.
Reliability is pretty much a solved problem (if the drive is powered up at least occasionally, i.e. not used as long term backup in a drawer somewhere); I think Samsung still has a spotless track record and is considered a safe option.
