Does anyone know if this card conflicts with a gigabyte gc-titan ridge thunderbolt 3 pcie card in a cmp 4,1 or 5,1?

There should not be any conflict.

Will this work with a dell xps 8940. i cannot find any documentation on dell's website regarding the single pci-e slot that's available?

No it won’t work on Dells. I found that out the hard way. Stick to Startech. I tried many and they are the only ones that work.

Does support pci 4.0? and does support window 10?

All Sonnet cards of all types support PCIe 4.0 slots and Windows 10.
