Hoping I can get some direction and thank you in advance. I have a mid 2010 27" iMac i5 and it has gotten unbarebly slow. Computer is used to run a small business which will include photo editing and website development. Video editing is done once in a blue moon just for family videos. I am not sure if I should go the route of buying a Mac Pro 4,1 or 5,1 and using my current iMac as a display or just buy a new iMac.
