Currently: MacPro 4.1 2.93 Quad Core Xeon with 24 gb memory AATI Radeon 5870 Samsung SSD as a start up disc. Budget $1600.00 The mac has been rock solid since I got it in 2009. I work in the current versions of Photoshop/Illustrator/Indesign CC 2015 (which are all beginning to feel pokey). I'm toying with the idea of upgrading the processor/ram through one of the tray upgrades on either Ebay or OWC. I've read enough Mac upgrade stories to be completely confused as to which processor would actually give me a worthwhile boost in speed in the apps listed. Any processor recommendations would be very welcome. Thanks!
