Hello - will Premiere Elements 2018 work with this GPU: NVIDIA Quadro M4000 8GB GDDR5? or perhaps the NVIDIA QuadroK2200 - 4GB GDDR5. The Adobe GPU PE supported list contains outdated products that generally will not support 4K editing at all!
Those graphics cards should work fine, but I don't believe Premier Elements uses GPU acceleration. Photoshop Elements does, but I believe only for 'Adjust Facial Features' editing functions. It's hard to find any GPU data on the latest 2018 versions, but that was the case for the 2015 versions.
