I just purchased an HP 750-116 it has an 3.60 gigahertz AMD A10-8750 Radeon R7, 12 Compute Cores 4C+8G processor, and I contacted HP support to see if the video card I found to add to my system would work with the motherboard, a Gigabyte GeForce GTX 970 Mini ITX Overclocked 4GB GDDR5 PCiE Video Card GV-N970IXOC-4GD. They told me that it was compatible, but I would have to upgrade the CPU in order to upgrade the video card. I have never heard of that and was wondering if that was true? from what I saw investigating the card, nowhere does it mention that the processor needs to be upgraded. Any advice would be appreciated.
