Hi everyone ! I'm after a bit of advice ... I currently own an early 2009 Mac Pro Desktop 2 x 2.26 Ghz Quad-Core Intel Xeon with 32Gb Ram and a NVIDIA GeForce GT 120 512 MB. I'm a photographer / videographer and i'm thinking maybe i need to upgrade my computer soon. Will i notice much of a performance improvement if i upgrade to either a new 27" 3.4ghz iMac with 32Gb Ram and a 1Tb Fusion Drive Or A new Mac Pro with 3.7GHz Quad-Core Intel Xeon E5 processor, 32Gb Ram and 1Tb PCIe- Flash Storage ? Obviously newer Macs will be a bit faster ... but how much so - especially if i consider an internal 1Tb SSD for my existing Dual Quad Core Mac Pro ? Are we talking about doubling the speed of Photoshop etc or just a slight improvement in performance ? Advice would be appreciated ... thanks !
