My hardware is a little weak in the meantime: Intel I7 6700K, Nvidia GTX 960. Therefore the renderingspeed is just 1,1 FPS. I tried to figure out if there is a difference using Encoder H264 high (Intel) or H264 high (Nvidia) when deinterlacing and upscaling DV-clips to FHD. There is no difference in speed AND no difference in workload of the HD Graphics 530 and the GTX 960. In both cases the task manager shows 1-2% for the HD Graphics 530 and 95-100% for the GTX 960. Why does the HD 530 work with just 1-2% using the Encoder Encoder H264 high (Intel)???
There are many factors to consider when choosing a graphics card, and the price fluctuates greatly. You should go to a more mainstream communication platform to discuss it. I suggest you choose an Nvidia graphics card with a reasonable price.
