Thank you for the information. I'm in the midst of getting a 27" iMac. Either late 2014 or late 2015.

It seems late 2014 seems like a better deal with slight edge in GPU too.

Exactly 100x.

Just kidding.

But seriously:

Sure about that? If you look closely, you might notice that there is no iMac with the 390x, only one with the 390. If your choice is between a 2014 iMac with a Radeon 290 and a 2015 model with the 390, the latter is (slightly) more performant. If it's between an 2014 iMac with a 290x and a 2015 version with just the 390, you are indeed correct.

it s that I m looking to buy a new computer and in the refurbished store I see all the options.. 290x, 390,AMD,Nvidea etc. Even refurbished they are pricy and I want to get the best model I can afford.I am even looking at Windows as well.While I'd prefer an iMac atm the Windows machines.. are looking tempting.
