I am selling my Mid 2011 iMac with upgraded i7Core running at 3.4GHz, Upgraded Storage of 1TB 3.1Ghz Storage, Upgraded AMD Radeon HD 6970M with 2GB GDDR5. These upgrades bring the current iMac to be on par with a late 2013 model based on the benchmark test below.

Just restored (factory reset) the OS X with an upgrade El Capitan and bundled the iMac with Adobe Creative Suite and Microsoft Office Pro.
Reason for selling: Upgrading to a new MacBook Pro
Sale offer last till 13 of April before being ship overseas to be sold.
