I just upgraded from my current non retina 27" iMac (late 2012) to the 27" retina 5K iMac (late 2014). Specs below:
iMac 27" non retina(late 2012)
3.4GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz
8GB 1600MHz DDR3 SDRAM - 2x4GB
1TB Serial ATA Drive @ 7200 rpm
NVIDIA GeForce GTX 675MX 1GB GDDR5
iMac 27" 5K retina(late 2014)
4.0GHz Quad-core Intel Core i7, Turbo Boost up to 4.4GHz
8GB 1600MHz DDR3 SDRAM - 2x4GB
1TB Flash Storage
AMD Radeon R9 M290X 2GB GDDR5
Think it was worth the upgrade or should have waited another generation or 2?
