I know their driver optimizations are poor for older directx versions, but my main focus is blender. Is it a good option for 3d work? I saw some videos published by intel demonstrating their gpu capability in blender and it looks pretty good.
Paraphrased from Gamers Nexus video;
If you want to waste your time with trying to get the drivers to work and have a lot of time in your hands, then yes Intel's discrete GPU's and their drivers are worth investing into. If you're someone who has a time is money mentality/mind set, then look at another brand of GPU...Intel need to refine their driver package.
