Then they are ignorant, so how does that help your argument that the AMD option is better? You also aren't considering what games they're playing, how often, if they have a desktop, etc.The vast majority is iGPU only. People play games on them.
Kaveri is decent for games on a laptop, but you can find Intel + dGPU laptops that are around the same price and have better performance and battery life. It's difficult for AMD to offer great value in this area considering Intel's CPU advantage and AMD's system memory solution for graphics.
If we're talking desktop, I see no reason to go with the APUs.
