Hi all I'm looking to buy a new iMac, preferably as soon as possible, this iMac will be used primarily to run Logic Pro X, other music production related software and web browsing. I currently have a Late 2009 27" iMac which has served me well, and still works fine. The reason I'm looking to upgrade is because the CPU and HD are constantly maxing out while using Logic Pro X which is stopping me from creating and finishing my music. The spec I'm looking at is: 27" 5k iMac i7 4.0ghz 32gb RAM (upgrading RAM myself) 512gb Flash Storage AMD Radeon R9 M390 2GB I'm aware that it is not recommended to buy one now due to a possible update before the end of the year, is it likely the update happening soon will be a complete re-design, faster CPU etc? I don't mind waiting until October but I don't want to wait if all they do is bump up the graphics card and add USB-C, both of which won't really affect how I use the iMac. Another question, is the graphics card I listed in the specs alright for also driving a 4k monitor? I won't be doing any gaming or graphically intensive processes on this iMac. In an ideal world for me, next week when they release the iPhone 7 they give the iMac a spec upgrade, or even better a complete re-design so that it's the perfect time to buy one. Help is appreciated, what would you do in my situation? Thanks!
