True, and many will approach DIY builds with that mindset.
My expectation is that pretty much anyone who is buying an i3-whatever type system is not going to know whether it actually has an i3-whatever inside or if it has an AMD A10/A8-whatever inside.
At that performance bracket people are spending $500 and not $1000 because they don't value the performance that comes in dropping $1k on speedy CPUs and ram. They are spending only $500 because that is all their computer is worth to them.
You are 100% correct, people buy a 500$ computer because that is what they believe a computer is worth. Only person I know with a dual GTX680 is on food stamps, disability, unemployed, and lives in a trailer park.
And yes if there is a form factor they like that is what they go for...
But what happens when there are two dozen computers at the store all at 500$ and all of them at the same form factor? (last I checked at brick and mortar store that was the case)
You can't even go by brand recognition because each brand has several computers in such form factors and price points using different components. (the big companies often have both AMD and intel CPUs and multiple builds)
At this point they are probably going to ask someone (clerk, family member, knowledgeable friend) "which is best" because they are going to want to FEEL like they are getting the most for their 500$. Yes they can afford more, but they are only willing to spend 500$ because they are frugal and frugal people don't like being "ripped off".
Now, if they don't care about video games then the A10 gives them nothing over the i3 because they DO NOT CARE about video game performance.
If they do care about video game performance then the A10 has to compete with an discrete GPUs from nvidia and AMD itself. Yes, you CAN get a discreet GPU in a system that cost 500$, it won't be the greatest dGPU but it will be faster than the A10. It can even still be both AMD GPU and AMD CPU even.
Yes the A10 is much much much better iGPU performance than the i3... but what is the target audience? Only place where I think this could possibly matter is in gaming laptops... at which point the horrible power inefficiency of the CPU will be a bitter pill to swallow for it (since a laptop is used for more then just gaming).
I hate linking Steam surveys but...

Trinity will work considering theres about 10% of steam users using Intel HD graphics and a whole whack load of mainstream gamers using 'utter crap' for dedicated gpus.
I am pretty sure those intel iGPU ones are from laptops.
I know I installed steam on my work laptop which has an intel iGPU and I use it to play some games like plants vs zombies.
I wanted to play more serious games but unfortunately that sucky intel iGPU cannot run them even on lowest settings.
And those "utter crap" dGPUs? How many of them are actually worse than the A10 APU?
