Hi i am using 970 gpu at the moment what is my best option for a quick cheap upgrade i was thinking eithe 1060 /1050 super any suggestions and i am not looking to spend over £400 i do not use my pc for gaming ,but i am editing 4k video /8k video the latter if and when suitable nle becomes viable ,even think my 42mp and 50mp sony files would benefit from a better gpu when editing lightroom/and plugins .
