My desktop runs on a Haswell, so I was relieved to find that I just made the cut. However, my older computer has a Core2Extreme CPU. I don't use it much now, but have been planning to hook it up to my TV as a media center & emulation machine. I'm hoping this patch won't have such a drastic effect for this use.
