Console gamers are not PC gamers, though. And your average PC gamer spends nowhere near that much on a graphics card either. Back then you got a hell of a lot of hardware for 600 bucks with the PS3 as well. Didn't go over well with the vast majority of gamers regardless. I think 500 bucks is already pushing it. Especially if we're looking at machines that'll ultimately deliver games that look exactly like the ones we're playing right now, except at ultra settings and with quicker loading times. Maybe some hard-to-notice RT goodies shrown in if we're lucky.
The gap between a PS4/One launch title (Killzone and Ryse respectively) and top of the line PS3/360 games (Gears 3 and Uncharted 3 for example) was pretty damn obvious. The quality gap between that Halo Infinite trailer and your average Uncharted 4 cut-scene is only perceptible if you're watching a Digital Foundry video. Maybe I'm wrong, but I suspect these machines will be hard sells for the average consumer unless they're priced incredibly competitively.
