Hey there, As a student I'm lucky enough to get quite hefty discount so I'm looking to get an Imac. The 2 spec I'm looking at are: 27" 2.9GHz Quad-core Intel Core i5, Turbo Boost up to 3.6GHz 8GB 1600MHz DDR3 SDRAM - 2x4GB 1TB Fusion Drive NVIDIA GeForce GTX 660M 512MB GDDR5 or 27" 3.2GHz Quad-core Intel Core i5, Turbo Boost up to 3.6GHz 8GB 1600MHz DDR3 SDRAM - 2x4GB 1TB Fusion Drive NVIDIA GeForce GTX 680MX 2GB GDDR5 I'd look to add additional RAM later. Primary use for this will not include editing either photography or video and there will be no rendering. It's simply a day to day device for internet (large number of tabs etc), HD video,and work. The prices are £1516 and £1777 respectively so a difference of £261. If i'm looking for this to last 3-5 years which is likely to be best and most necessary? If you think a different spec would be better please throw in ideas! Much appreciated!
