Hey all. I'm on the fence now. I currently have a 2011 Imac with 3.4 ghz core i7 and 16 gb ram. I want to update to the new imac 5k screen but i think i should wait for the next model with the new skylake cpu by intel and hopefully see a Nvidia GPU instead of AMD. do you guys forsee any upcoming new imac releases with those specs? Thank you!
