Hi, I’m Alex, a Freelance 3D Generalist, Motion Designer and Compositor.

I’ve built a multitude of Computers, Workstations and Renderfarms and love to optimize them as much as possible.

Feel free to comment and ask for suggestions on your PC-Build or 3D-related Problem, I’ll do my best to help out!



1.I use blender cycle render the render take 27 sec to “synchronize object” and loading image but use only 3 sec to finish the tile and denoise.

I notice that it is very slow when loading texture like when switch from solid mode to lookdev.

2.When playing animation that model has 30,700 of vertices it can’t keep viewport at 30FPS. I’m working in solid mode and model have no modify except rigify rig armature then set playback to Nosync. Really weird.

Is there any way to fix it or some part of PC that can upgrade?

Hi Alex,

Firstly I’d like to say this website has been a huge help in helping me decide what parts to buy. I work as a freelance animator/director and do a range of jobs between CG character animation (Maya) to 2D storyboarding/concepting and some 3D modelling. I’ve been mainly wanting to upgrade my 5 year old rig and have been doing more redshift CG work, mostly as static proof of concept styleframes for pitching purposes. My maximum budget is around 5500 USD and would like your input on the following specs I’ve put together. My main questions are regarding the power supply – if it’s enough to power the specs and also if I have sufficient cooling.

Case: Fractal Design Define XL R2
CPU: Intel Core i9 9900K Octa Core LGA 1151 3.60GHz Unlocked CPU Processor
CPU Cooler: Noctua NH-D15 Multi-Socket PWM CPU Cooler
Mbboard: ASUS PRIME Z390-A LGA 1151 ATX Motherboard
Memory: 2X Corsair Vengeance LPX 32GB (2x 16GB) DDR4 CL15 3000MHz Memory
Hard Drives: Samsung 970 EVO Plus 1TB NVMe
Seagate ST4000DM004 4TB BarraCuda 3.5″ SATA3 Desktop Hard Drive
PSU: Corsair AX1200i 1200W Digital 80+ Platinum Modular Power Supply
GPU: 2X ASUS GeForce RTX 2080 Ti Turbo 11GB Video Card

Hey Alex,

I’m coming from the mac side and finally jumping into PC as I’ve fallen in love with Blender. In the very near future I will be branching out to C4D as well as Maya and ZBrush. I do a lot compositing currently in BFX Silhoutte and AE using Trapcode in a lot of my work. Currently running on the 2019 macbook bro i9-8core and an EGPU housing an RTX 2080ti.

My background is in video editing and aside from that, as it stands all of my workflows suffer – AE, Blender, even Silhouette. I soon will be using Octane and based on one of the articles here, am curious about Corona.

My question is a bit layered – I need fast viewport performance and I know you’ve mentioned the 3990x isn’t a great option for this. But I also detrimentally need to not be stuck waiting 5-6 hours everytime I send a composite pass in AE. (Usually my workflow entails 3-4 passes on one shot alone before it’s complete). So cutting my render times down there matters greatly. I’m wondering if I can offset some of the performance lost in viewport on a 3990x build by using Octane with a good GPU set up (referring to Blender/C4D etc…)

Currently looking at this build money is no issue as I’m leasing the purchase. My time is priceless these days and I’m sick of spending 7 days on a shot that should take 2.

Threadripper 3990X 64 core processor
360mm AIO liquid cooler from NZXT Or Corsair
128GB DDR4 3200mhz+ RAM
2TB NVME super speed PCIE 4.0 Drive – main
6TB mechanical storage drive
1200W Seasonic Platinum Prime PSU

*One note – I”m undecided as to wether to get two Titans or two 2080tis… I’ve seen a lot of really impressive benchmarks on the Titans as single GPUS. And have noticed that NVLINK in either case doesn’t really do much. Can you shed some light here?


Hi Alex,

I’m working on 3D renders (C4D,Octane,Blender,Redshift etc…) and motion design (After Effect, Photoshop,Illustrator, Nuke etc…) and I need to build my new machine. So I was wondering if you could take a look at the build below and check that there are no issues or incompatibilities between components.

CPU : AMD Ryzen 9 3900X
CPU COOLER : Corsair H115i Platinium
MEMORY (RAM) : Corsair Vengeance LPX Black DDR4 2 x 32 Go 2666 MHz CAS 16
GRAPHICS CARD : MSI GeForce RTX 2070 Ventus GP
SSD : Kingston KC2500 – 250 Go
STORAGE : Seagate BarraCuda – 2 To – 256 Mo
CASE : Cooler Master Masterbox MB511 TG RGB – Noir
POWER SUPPLY : Corsair RM850

I have a doubt about the compatibility between the RAM and the Motherboard…but maybe it’s okay.

Thanks in advance!


I do photo editing, graphic design, want to get into video editing for small youtube type projects not an independent film, and I want to be able to do serious work on interior/exterior home designs and renderings (room flythrough animations). I have gone through some of your articles but I see 3 different builds based on what I want to do with my computer. What build would be best to combine all of these interests? I am not into gaming but I want a good machine under hopefully 2k that can handle some big but not huge projects. Main software list is Photoshop, Lightroom, Illustrator, Premier Pro, Blender.

Thanks in advance!

Hey Steve,

Thanks for asking!

Here’s a very capable all-rounder build that for your use case: Parts List:

CPU: AMD Ryzen 9 3900X 3.8GHz 12-Core Processor ($415.00)
CPU Cooler: be quiet! Dark Rock Pro 4 AM4 ($89.90)
Motherboard: ASUS Pro WS X570-ACE ATX AM4 ($379.99)
GPU: NVIDIA RTX 2070 SUPER 8GB – MSI Gaming X ($569.99)
Memory: 32GB (2 x 16GB) Corsair Vengeance LPX DDR4-3200 CL16 ($159.99)
Storage PCIe-SSD: Samsung 970 PRO 512GB M.2 Solid State Drive ($149.99)
Power Supply: Corsair RMx Series Platinum RM850x 850W Power Supply ($127.21)
Case: Corsair Carbide Series 275Q ATX Mid Tower Case ($105.73)

The total cost of the build comes up to around $1997.80 but you can expect the Ryzen 9 3900X CPU and 32GB of RAM to deliver an excellent performance in terms of making your workflow fast and smooth. This build also comes with an RTX 2070 Super graphics card that delivers a better GPU render performance thanks to its support for CUDA core acceleration. All in all, this build should be more than powerful enough to handle your projects.



I ordered everything for my pc-builder except for the Power Supply. The pc-builder recommended a CORSAIR RM850x which is not available on amazon, best buy, or newegg. What other power supply units will work for my build that requires around 390 Watts (


Hi Alex,

thanks a lot for your useful tips on this site. Without previous experience, I was able to build my new CG workstation. This was amazing! 🙂

I am using:

– Ryzen 3900 CPU
– Pro WS X570-ACE Motherboard
– MSI Geforce RTX 2070 Super, OC-Ventus
– RM 850x power supply

This combination worked so far.
Now I bought a second gpu, same model.

When trying to boot the workstation with 2 similar gpu’s, only one graphics is detected. The other one does not start it’s fans.
I switched the cards to test if the new one might be damaged, but seperately used, both work fine.
Now when I have two gpu’s connected to my power supply (there are two slots for pci-e provided) none of the cards starts up. Only when I remove power from the second one, the first will start.

I also switched cables once to make sure it is not because of a damaged cable.

By the way, I did not buy a sli-bridge so far, if that matters…

Do you have any suggestions what I could be looking for?
Would be really helpful to get a hint. Thanks for your great work here!

Thanks & cheers,


Hi Alex,

I like the build ( you suggested for a rendering station. I have no experience assembling computers and find the idea of practicing these skills with the $5K budget as a risky one. I would very much appreciate it if you could suggest the practical way of hiring someone (person or small business) for the job as well as a ballpark number for such labor/services.

Thank you,


Hi Alex,

I was wondering if you could take a look at the build below, I’ve been saving for a while to build myself a machine that will last for a good few years. My old machine is struggling to cope and I need to build my new workhorse. Mainly I will working on 3D renders and game creation, with a break when the next GTA comes out. Holding back on getting an top range graphics card until the RTX 3000 range comes out (hopefully this year). Anyway enough prattle, see what you think, all ideas welcome.

Graphic Card GIGABYTE GeForce GTX 1660 Ti OC 6G 
Memory Trident Z Neo DDR4-3200MHz CL16-18-18-38 1.35V 128GB (4x32GB)

Hey Elliot,

Thanks for asking!

No issues really with your build but you might want to change your PSU to something with a higher wattage like the Corsair HX850i just to give you more headroom for when you upgrade to a higher-tiered graphics card. Other than that, you’re good good to go!



Thanks for the swift response, much appreciated.


Hi Alex,
Quick question: Do I need an sli bridge to render with multiple gpu’s in redshift?
Thank you again for your expertise and advice thus far!!

Alex Glawion

Hey Hans,
Nope, you won’t need any kind of bridge to use multiple GPUs in Redshift. There is the option of an NVLINK Bridge to increase your VRAM capacity between 2 gpus though, but in my experience in 99% of the cases this is entirely unnecessary.
