I decided when Apple introduced the 5k iMac to wait till the next version, the "upgrade" last week has me wondering/worrying if we will actually see a real upgraded version of the retina iMac this year. I don't follow the major GPU and CPU news anymore so i really don't know when intel, AMD and Nvidia is expected to release new products at this point. What we can expect as far as CPU and GPU for it? When is it likely to be released? And when should we have a better idea of what we can expect? I am considering getting a PC instead of the iMac and would be helpful to have a better idea.
