 +(updated: 2023.01)
 +
 +  * free blender-octane-edition download: (also available for Unreal+DAZ)
 +    - reg acc: https://account.otoy.com/sign_up
 +    - install BlenderOctaneEdition (octane render prime for BL) + OctaneServerPrime: https://render.otoy.com/shop/prime.php
 +    - run OctaneServerPrime, (octane icon at win tray)
 +      - it may ask you to download and put cudnn library, just click its Download button, it will do everything for you.
 +      - once done
 +      - click Active button, and login in pop windown, then it shows status: activated for 1 month (need stay online)
 +    - start OctaneBlenderEdition, the app root: C:\Program Files\BlenderOctane\
 +      - activate Octane plugin in Edit > Preference > Addon
 +      - also, Window > Octane DB to load all the material presets
 +    - basic initial setup
 +      - Render Property Tab: engine = Octane
 +      - select main cam, Camera tab: check "Octane Camera Imager", and > Tone Mapping: Response type: sRGB
 +      - Render Property Tab: Color Management > View Transform: RAW, gamma = 1
 +      - Environment tab: Octane Environment = daylight environment

 +====== Octane GPU Render Hardware ======
 +
 +  * Octane render speed (version 3 and 4) directly related to GPU power and count
 +    * octane 3.07 and below don't support RTX 20xx and GTX 16xx GPU,
 +    * octane 3.08 and 4 above support RTX 20xx and GTX 16xx GPU,
 +    * octane 3 and octane 4 use different benchmark points

 +  * Conclusion:
 +    * (3300 SGD budget - 588 @O4) for RTX 2080 or 2080 Ti? 
 +      * Go for **2x RTX 2080 Ti**, it is better than 3x RTX 2080 setup, 4 PCI-E connection better to manage.
 +    * (2200 SGD budget **621** @04) for 2x RTX 2080 or 3x RTX 2070?
 +      * definitely for **3x RTX 2070**, only 3 PCI-E connection to manage and 50% more power. 
 +    * (700 SGD budget **209** @O4) RTX 2070 vs GTX 1080 Ti 2nd hand?
 +      * for octane 4, definitely go for RTX 2070, it is better and newer
 +      * for octane 3, you can only go for 1080 Ti
 +    * (700 SGD budget **312** @04 2nd hand) RTX 2070 vs GTX 1070 Ti 2nd hand?
 +      * for price of RTX 2070, you can get **2x GTX 1070 Ti 2nd price**. 
 +
 +**Final Conclusion**
 +    * 2070 and 1070 single 8pin PCI-E power connection is great for multi-GPU and easy Power Supply setup. as even 850W PSU can power 3 of them.
 +    * for 2nd hand price, it is better to buy 3x GTX 1070 Ti at 380x3 = 1140 SGD with 850W PUS (140SGD).
 +      * total = 446 @ O4 score, best for price, only outperformed by 3x GTX1080 Ti (more expensive)
 +    * for brand new card, it is better to buy 3x RTX 2070 at 710x3 = 2130 SGD with 850W PUS (140SGD).
 +      * total = 621 @ O4 score, best for price, only outperformed by 3x 2080 Ti (more than double price.)

 +===== Power Supply Connection Consideration =====

 +| PSU (Seasonic)   | Connector     | cost2022 |
 +| gm750W  |              | 150 |
 +| s12iii 650w |          | 93 |
 +| PSU (Seasonic)   | Connector     | cost2019 |
 +| S12II 520W | 2 PCI-E max | 75       |
 +| S12II 620W | 2 PCI-E max | 91       |
 +| M12II 850W | 3 PCI-E max | 140      |
 +| PrimeUltra1000GD | 4 PCI-E | 240     |
 +| Prime 1300GD | 6 PCI-E   | 293       | 
 +
 +===== Motherboard PCI-E x16 Port Count =====
 +
 +  - **for mATX motherboard, maximum 2 GPU can be plugged**. (PCI-E 3.0 x16 + PCI-E 2.0 x4)
 +    * and 2nd slot may block front panel pin connection, so you can use front usb
 +    * example: Asrock B350m Pro4
 +  - **for ATX motherboard, maximum 2 GPU for cheap board**, and you have free room for front panel pin connection
 +    * example: Asrock B350 Pro4, B450 Pro4
 +  - **for better ATX motherboard, maximum 3 GPU can be plugged** (PCI-E 3.0 x8 + PCI-E 3.0 x8 + PCI-E 2.0 x4)
 +    * however, some motherboard pin may be blocked by last GPU, but some motherboard has better pin arrangement for this issue
 +    * example: 
 +      * Asrock X370 Taichi
 +      * MSI X370/X470 GAMING PLUS AM4
 +  - **For 4x GPU or better 3x GPU setup**, only high-end CPU board, like X399 series board for AMD TR 2950X can have 4 slot
 +    * some cheap x399 board has 4 slot, but spacing is better which cause only 3 slot can take GPU, like MSI MEG X399 CREATION sTR4 
 +    * example:
 +      * ASRock X399 Taichi sTR4, Asrock Fatal1ty X399, 4 Slot with 2 card spacing.
 +      * GIGABYTE X399 AORUS Gaming 7 sTR4 has 5 slot, but only 4 slot can be used to take 2 card spacing
 +
 +
 +
 +**Additional Concern**
 +  * some riser card may solve the block pin issue, but not ideal for both case and stability

 +
 +===== GPU fan type Blower vs Fan and GPU Size =====
 +
 +  * for 3 GPU setup or better 2 GPU, those motherboards are better spaced for either fan design type GPU, but of course, Trip fan type are better than blower type in this case
 +  * for 4 GPU setup or those 4 slot motherboard, due to 2 card slot spacing, Blower type is prefered to avoid GPU heat causing clock speed capped.
 +  * Better Casing cooling and Case fan flow control (cleaning and maintain dusts) are always better to keep GPU at high load.
 +
 +  * Those multiple GPU oriented maker all make blower type, like leadtek, zotac, and of course expensive Asus.
 +
 +  * Compare Blower and Fan type extreme case:

 +
 +
 +**GPU if too long, it can also block SATA connectors and USB3 contector in some case**
 +  * like leadtek GTX 1070 Ti WindForce is too long in some case and motherboard combination
 +  * some small card like Zotac 1070 Ti mini is small like normal 1060 cards, can fit better in either main slot or last GPU slot without causing pin blocking.
