Hey guys! I could really use your help! I am a Mac user on a budget so I have to go refurb. The price difference is about 425 dollars between the two models listed below. I really want the 27in Imac but I am wondering if I should maybe save the 420$ and put that into software for the computer accessories (add to savings )etc. I plan on doing some music producing and minimal video editing, music, more casual kind of use plus school. I am just wondering besides the screen improvement is the 420$ upgrade for a better GPU and Graphic's Card going to be worth the money? I think the 27 would have a better workflow with the extra space? http://store.apple.com/us/product/FD093LL/A/refurbished-imac-27ghz-quad-core-intel-core-i5 21.5-inch LED-backlit glossy widescreen display 8GB memory 1TB hard drive NVIDIA GeForce GT 640M with 512MB 2.7ghz http://store.apple.com/us/product/FD095LL/A/refurbished-imac-29ghz-quad-core-intel-core-i5 27-inch LED-backlit display with IPS technology 8GB memory 1TB hard drive NVIDIA GeForce GTX 660M with 512MB 2.9ghz Thanks for all your help I am hoping to purchase later tonight upon your feedback!
