I am buying a new imac to replace by early 2007 MBP. I'll game on it if things run well but mostly photoshop, indesign and a few other adobe programs. Then your basic internet, music, netflix etc. I like the drop in the refurb prices but since I most likely will not buy again for 4 or 5 years is the 802.11ac wifi going to matter? Will I need a new router to see the difference? I'll be getting either: Refurb option Originally released October 2012 27-inch LED-backlit display with IPS technology 8GB memory 1TB Fusion Drive NVIDIA GeForce GTX 680MX with 2GB I think this has plenty of power for now, its cheaper and I may run bootcamp to game eventually but I use an Xbox alot and really am only excited for Star Craft 2 at the moment. Then there is 3.5GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz 8GB 1600MHz DDR3 SDRAM - 2X4GB 1TB Fusion Drive NVIDIA GeForce GTX 780M 4GB GDDR5 I am a student so with apple care it is around $400 more. I like the savings but $400 is not that much to pull an extra year or two out of the machine. I know this new one is overkill at the moment but wil the new wifi be worth it?
