Question / Help Multiple 4k cameras recorded with a PC + OBS

Hi everyone!

I am looking for some guidance and to see if anyone had experience with the setup I am planning to do. I would like to create a PC which will run OBS and will be used to record a 3 camera 4K greenbox setup. I am planning on using three Blackmagic capture cards. Ideally, I would like to use chroma keying whilst recording, but if it is too hardware intensive then that will be done later on. Obviously this would be a budget version of the more serious, broadcast type equipment designed for such use...

Has anyone attempted such a setup before? My worry is that there will be some delay and that the hardware won't be able to keep up with 3 simultaneous 4K signal + the chroma keying.

Many thanks for any input on this!
