I'm currently using a MBP 2010 and looking to make a purchase on a fully upgraded MBP. But im wondering if it is better to wait for the 2018 version since its basically 3 months away. Should i spend the 4100$ now or get the base model Imac pro for 4999 or wait for the 2018 mbp and get that one fully upgraded? im using this strictly for 4k editing on fcp and adobe premiere pro cc. Also a lot of photo editing with photoshop and lightroom. My 2010 is way to slow rendering video and trying to preview the video on the software even when its 1080p is super choppy. ive been able to make it due for now though.
