iMac Upgrade hierarchy

[nagareru]

There are a lot of people who make new threads asking what should they upgrade ram cpu gpu. So, generally speaking, what do you guys think is the most important upgrade. For me, if I had to choose the most important one, would be the CPU.

Cpu > ram > gpu

Depends upon what you need the iMac to do.

GPU > CPU > Fusion Drive > RAM

The CPU, HD, and RAM are upgradable, while the GPU is not, based on the 21.5" teardown by iFixit. This order also indicates the difficulty of upgrading each component as well.
