It's kind of double-edged sword TBH - many average Joes who but consoles at local stores will ask why one is is more expensive than the other, and they will hear it's because it has more powerful GPU, with more TFlops, but average Joe doesn't know what a TF is, many of them don't even know what a GPU is, they just think there is this one, magical "processor" that does all the job (which is actually true given more and more consumer electronics use SoC solutions nowadays), but at the end of the day, they will look at both screen, and say "hey, this CoD looks EXACTLY like the other CoD, I don't see this console being any more powerful" - and will easily pick up the cheaper console.
But on the other hand, once more and more titles show up, and with them more and more reviews, the more powerful console will have a free marketing, being able to nitpick lines like "plays best on XYZ", "XYZ has a great advantage", "XYZ clearly wins this gen" and so on, and put them on every possible trailer, TV spot, banner, poster etc., and the consumers will take notice, and many of them will blindly follow and pick that XYZ console not even digging into the details.
