Well I sold my iMac earlier this year and got a gaming PC. I really don't like Windows and decided to go back to OSX. Getting a 34" LG Ultra Wide Screen. Just bought a 2012 2.6Ghz i7 with 16Gb RAM from eBay and will put both my 240Gb SSD's in it. Is the HD4000 running El Capitan ok? The res of the LG is 3440x1440. I won't be gaming on it but use Safari, Mail, Photoshop, Lightroom and Office 2016. Sounds like a powerful little machine on paper and looking forward to getting it.
