Putting together a computer that will be running vMix. The goal is for it to have the ability to record four 4k cameras. vMix recommends a 960/1060 for two 4k cameras, so I'm wondering what four would need. There is a pretty big performance gap between a 960 and 1060. Anybody have experience with this many 4k camera? Do you think a 1060 6gb would be enough?

Thanks.
