Quick question about new components
I've been operating on a GTX 960 4GB for about 5 years and it recently occured to me that I am worth more than that. I deserve to be happy too, life is short.
So I'm looking for a RTX 2080 that will ship from the US and I think I found it. I just have a couple of quick questions. My hardware experience is installing two RAM cards :p
I think I probably need to upgrade my PSU as well. I showed it to a friend with computer experience and he laughed at me and said it was weak. I'm not sure what I should be looking at and I'm equally unsure about what PSU to get :p
Also, I hear size is a big factor for GPU. I think I have a decent amount of room in my case. The GPU I have looks pretty short compared to the picture of the new one but I should be good right? They all seem to be about the same width.
If anyone could give me a recommendation, I'd very much appreciate it.
Thanks!
Oh! Please see attached photos ☺️

You should be able to get the dimensions of the GPU - length is going to be the worry, you have enough width and height is standard as far as I know. It would be a good diea to post your system details. As for the PSU, it is important to bear the age in mind - if this is an older system you may be better off replacing it even if the rating is up to the task in theory.
If this is a 5 year old 600W power supply, you should be ok.
I'd advise against the RTX 2080 though, unless the price is special.
The newer refreshed RTX 2070 Super uses less power, is smaller, cheaper, and faster in iRay.

Why go overboard?! What are your plans?!
600W is quite alright and if you choose to buy a good system, it can be quite enough for almost everything. There are cpu's out there like Ryzen 7 3700X, that need not much power (35W eco) but have crazy abilities. I recommend to buy a better cooler like the NOCTUA NH-D15. It's the best way to go, since it is usable with the most of the systems out there and cools the CPU very good. 32GB DDR 4 (3200) and you are fine for the next few years. What is important at the moment is an SSD, with great influence for the loading times (reading, writing). I recommend not to buy standarts like Samsung Evo, but look instead for grabs like Toshiba RD500 NVMe SSD 1000GB M.2 2280 PCIe 3.0 x4. They are brutal fast, also the 500 GB of the same series.
Then again, there are also Geforce Cards out there, which need not so much power, so you could use two instead of one card. I would say wait for a ti card or buy one that is already out there. Check what it would be worth:

*Update just saw this by the way...
https://gpu.userbenchmark.com/Compare/Nvidia-RTX-2070S-Super-vs-Nvidia-GTX-1080-Ti/4048vs3918 (...but keep in mind, the 1080 ti needs also more power, so a slight change to a higher PSU would be needet, interesting is the price and comparsion)
I'd recommend a ASUS Cerberus GeForce GTX 1070 Ti Advanced 8GB GDDR5. Two of them in fact, if you can get your hands on two. I know, some may disagree here, but with the right render settings you don't need hours to render a frame or even an animation. Think about it, you may buy a older card, but you buy two of them, that will be able to run just fine with this "setup" and since the card is around 40-50% less expensive, you are able to get a faster rendering process for a lower price. As a board i would recommend anything without an active cooling process (every time ...) and with two M.2 slots for two SSD's. Also an older model, but still powerful: MSI X470 Gaming Plus Max
Everything is powered by: be quiet! PURE POWER 11 | 600W CM (the cm only means that the cables can be attached so you only clip what you need and it has a peek max of 650W)
Everything was tested with many different render options:
Blender 1.79, 1.82, 1.83, 1.90 evee and cycles, DAZ Studio 4.12 (64-bit) Iray & 3Dlight, Multiple stress and benchmark tests for different render engines and i even participated in a open render farm project a few weeks with CPU & GPU 1, while working with Blender and rendering with GPU 0. Overall i had not many renders that went over 1-10 minutes to render, but i cannot speak for every scene possible here.
By the way, Nvidia seems to work hard on their drivers. Since i bought the first card many things have changed and the card is now even able to render with OptiX, which was not possible at first. In fact many older cards can do so now, so you have a lot of options here.
What tower you have would be also interesting, but by the looks of it there is quite enough room. I also have a smaler case: be quiet! PURE BASE 500 | BLACK
Whoa whoa!! Hold up here....I can use 2 GPU's at the same time? I thought I heard that Iray doesn't recognize SLI (which is what I think the 2 GPU thing means). Like...it only looks for/works with one GPU when rendering. And also, just to be clear, I wasn't looking at building a new system. I just want a better GPU and wasn't sure if my current PSU would power it. The 2070 Super for instance says "System PSU Limitation: 650W" so I think I do need something beefier. But still, this 2 GPU thing has my attention!
Yes, you can use multiple GPU's for rendering (and they don't have to be connected via SLI or NVLink bridges). Iray has the ability to utilize multiple GPU's in parallel for rendering, although due to some limitations in the Iray scheduler you will not see a 2x improvement in rendering with 2 identical cards (rather, something like 80-90% improvement). The two GPU's don't even have to be the same model, but they must both be NVidia cards with CUDA cores to use Iray. You can also use your GPU and CPU together as well, but since in general GPU's are much faster in rendering using Iray than CPU's (unless you have a very high end CPU), the performance improvement is very small. The thread below shows the effect of several multiple and single GPU setups measured against rendering times on a benchmark scene (note some of the benchmark runs use up to 4 GPU's!)--you can use this to get an approximation of what to expect if you upgrade your system. Please note that if you do choose to run 2 GPU's your power supply must be able to support both of them running at the same time, so be sure to check the power usage of the GPU you want to buy.

Wow! I swear I asked a question similar to this years ago when I first started and was told Daz only recognized one GPU at a time. So I can add a new GPU and slot my GTX 960 as well and and it's 1000 or so Cuda Cores and 4GB to the new one and end up with 12GB of GPU?! System allowing of course. I'm not asking that anyone know my computer make up. But speaking strictly of GPU...does that stand up?
Iray has always been able to use multiple GPUs in DS, I'm pretty certain.
Well then I was listening to the wrong people! All this time! Wow! Well that is awesome news. Thank you everyone for the eye opening information!
Pooling your VRAM can only be done using SLI (not sure if DAZ supports this) or NVLink (which I believe requires 2 of the same GPU types to work). I don't believe you will be able to link a newer 8 GB card to your current 4 GB 960 to pool their VRAM together. However, if your scene is small enough to fit independently on both video cards (in your case, if your scene requires less than 4 GB VRAM), if you have 2 or more GPU's installed the scene will be sent to both cards and rendered effectively simultaneously which will speed up your render times (how much improvement will depend on the relative rendering speed of each individual card). Again, the benchmark page I listed above can be used to get an idea of performance improvements for various multi-GPU setups. If your scene is >4 GB but less than 8 GB, the 960 will drop out of the render but the newer card will still be used, so all is not lost on that front. Only if your scene is > 8 GB will the scene drop off GPU altogether and fall back to CPU rendering if you have it enabled.
Memory pooling (with a speed penalty) only using nvLink between identical cards - SLI doesn't offer it, and older versions of Iray don't support it anyway.
