I've been asked to put together some options for my church that does 3 services live streamed, recorded, and edited every weekend (plus a few other odds and ends). They plan to use Adobe Premier, and a live streaming service (can't remember the name of the program off the top of my head). They record and stream in 1080p, 480, and possibly one lower resolution for people with bad connections. They would prefer a mac, but the board has asked them to price up a similar PC to see if it will save money. I already mentioned that parts will not be a "package" deal this way (i.e. parts will be individually warranted and it will have to be more closely managed). So, we have to meet or exceed performance of their proposed top-of-the-line iMac: 27" 5k display (not sure if we need to include this or not, they already have a 27" 1440p apple monitor), quad core intel i7 processor, 32GB 1867mhz DDR3 RAM, 2TB fusion drive, and Radeon R9 M395X (4GB). The mac price is $3500, but our goal here is to beat that price. I also already told them that the experience between Final Cut Pro and Adobe Premier will be different, and they understand that. A little extra rendering time is fine for them as long as streaming doesn't drop frames at the resolutions above and price is better than the mac. So, my questions - what would be a good build for under $3500 (pref around $2000) that's good at video editing and streaming? I'm thinking i7-E series, 32GB DDR4 (if possible), m.2 OS and programs drive (128-256GB), 4TB storage and working drive, and whatever graphics card will be best for Adobe (nVidia / AMD?). Thoughts?
