System Intel I7 3930K, core speed 4500.04, Graphics card GTX670, I overclocked this system about 4 years ago. I would like to upgrade the graphics card to, ZOTAC nVidia GeForce GTX 1060 3GB 4K. My problem I would need to update the bios to the latest version I think which would disable my overclock, I am now 74 and find it difficult to concentrate, any ideas would be much appreciated.
