I recently upgraded the GPU in a Dell T5810 workstation from an Nvidia Quadro M4000 (8 GB) to an MSI GTX 1660 Super (6 GB). The changes I see are a bit puzzling to me. I am hoping you can help explain what I see and offer guidance on two questions regarding a possible next GPU upgrade.
The Dell Precision Workstation T5810, 4 years old, key specs:
- Xeon E5-1660 v4, 8 cores, 3.8 GHz
- 64 GB RAM, 2400 MHz DDR4
- 2 1TB PCIe m.2 NVMe SSDs (one for Windows + apps, one for data)
- Windows 10 Pro 64-bit
- ON1 Photo Raw 2021 64-bit image editing app
The demanding application is photographic image editing using ON1 Photo Raw. In particular, the most-demanding task seems to be creating an image mask of a complex object (e.g. isolate a squirrel or some birds from a larger background of trees and flowers). It sends the GPU temperature up and activates the GPU's fans.
OLD GPU: NVIDIA Quadro M4000, 8 GB RAM
NEW GPU: MSI GTX 1660 Super, 6 GB RAM
With the Quadro all aspects of sorting and editing images were irritatingly slow although with help from many experts I found ways to improve the situation (see
https://www.experts-exchange.com/questions/29218666/Hardware-and-migration-decisions-replacing-Dell-Workstation-to-improve-performance-editing-images.html?preview=ndn0YvXLhs3KR9gagOp1dA%3D%3D).
With the new GTX 1660 Super GPU I find:
- Overall working with ON1 2021 Photo Raw is now manageable.
- Sorting and selecting images is hugely faster.
- Creating masks (as described above) is somewhat faster and more responsive although there is still some hesitation and "jerkiness" in operation.
- Other aspects of editing have more improvement than creating masks.
- While it is manageable and a lot better, I would prefer to get it even more responsive.
T5810-based constraints for any new GPU:
- System power supply is 685 Watts.
- GPU PCIE x16 slot rated for 225 Watts maximum.
- Space is tight; can only use a dual-width GPU.
The puzzle in a nutshell: The MSI GTX 1660 Super card uses DirectX (12). PassMark overall is better than the Quadro M4000. But 2D graphics is slightly worse than the M4000. 3D graphics is much better.

For image editing it seems to me that 2D performance is more important than 3D performance.
So perhaps we explain the varied improvements I see due to using DirectX and perhaps faster GPU operation but limited by reduced 2D capability?
QUESTION 1: Does my conclusion make sense to you? Do you see other explanations? I am trying to understand this situation as deeply as possible.
QUESTION 2: If 2D capability is what's most important is there a way to know how a particular GPU does on 2D? (Likely candidates are RTX 3060, 3060 ti, 3070. And Radeon 5700 XT. Higher versions tend to be too deep or require too much power.)
QUESTION 3: Is there something different I should be considering to further improve the image editing performance?
