Not that I have a definite answer (don't have the models you mention) but my experience is that the intensity range doesn't support Resolve. If you look at the current Blackmagic site you'll see that Resolve is not listed on any Intensity product as compatible. Only the Decklink range is.
I was at a clients place and they are running Resolve Lite with an intensity HDMI PCIe card which works and is shown in the video I/O panel.
I would say though that I think it is only 8 bit and if you have a broadcast monitor it seems a shame to be in 8 bit for the sake of a couple of hundred dollars. There are places to skimp but picture monitoring isn't one of them IMO.
