Is the 21.5″ Retina 4K display iMac 2015 worth it?
With a new, much better screen and updated specs the 4K iMac has a lot going for it but are the Intel Iris Graphics 6200 enough to handle the retina display? How does it perform for gaming? And with a base 1TB 5400RPM hard drive does the base 2015 21″ iMac even make sense?
