A P2000 doesn't use even near the bandwidth limitations of 16 lanes of PCI Gen3. You can easily run it in x8 mode or PCI Gen2 mode. That leaves plenty of room for activities.
My latest CasparCG build uses an i5-6600k, 16GB Ram, an RX 580 and a Decklink 8K Pro outputting 2 fills and 2 keys with about 15 layers being composited at any given time in 4K 29.97p and still doesn't break a sweat in production.
That's very interesting. I am considering the 8K Pro too.
On my Desktop with a GTX770 I already have issues with 2 1080p60 Outputs, the 2GB of VRAM are full and I see 100% Copy load in task Manager, however this is without a decklink and using screen Containers. This made me worried about storage bandwith. The P2000 has even less bandwith than my GTX.
I think Threadripper will still be beneficial for Software encoding or in case I will add a second decklink later.
Yeah VRAM is definitely an issue, this setup was almost working with a K4000 but I would get some audio stutter when playing both channels at once.
I don't think you gain any efficiency using the decklink producer versus the screen one. As far as storage bandwidth goes we fetch the media via NFS on a very standard 1gbps ethernet network so that really shouldn't be an issue unless you're trying to composite multiple 200mbps+ files at once.

You can used the Intel X series which is 48 Pci-e lane.
