can any let me know if easy worship is more CPU intensive or graphics card intensive for 1080p words on screen

Depends on which Build it is. 7.1.4.2 and previous uses more CPU while the latest 7.2.3.0 uses more GPU.  If you have an older system, or trying to use one with onboard Intel graphics (which are NOT supported) or lower end Nvidia GT cards I would go with 7.1.4.2. If you have a newer system with Nvidia GTX or RTX Graphics card 7.2.3.0 will be fine.

See the System Requirements For EasyWorship Page to see what EW recommends. For 1080p you want to use the RECOMMENDED list.
