New RiMac for Final Cut X

[4dtough]

Just a question who is using one?
What options do you have ?
DO you do 1080 or 4K video
do you have any issues?
Why did you choose iMac over MacPro Mini?
Thank you and sorry for all the questions
I will be buying one and just wondering what and why people selected what they have.
I currently have 12 core MacPro, 2.4 and its just lost a video card so its time to look at something new.
Thank you for all your help
