Dumb argument, and here's why:
This is like comparing driving a car to driving a moped. Both do the same thing (get you from A to B), one just has waaaaaaaaay more power under the hood and is much more costly.
Stupid topic reason #1: If you're spending an astronomical amount of money on graphics cards, processors, RAM, and the such JUST for gaming you have to consider the type of games you play with what type of hardware you're getting. OP assumes all PC Gamers intend to outright spend a vast amount of money on mid to high-end shit when a good majority of PC games require nowhere near $200-300 video cards. Most people I know honestly buy this expensive shit just to see how high their shit can go, but have no real specific reason to have it. If they're spending $300 on high-end cards and then playing a game like League of Legends, it's their own fault or they have an ego problem when they brag about 4-5 FPS increases.
Stupid topic reason #2: You're also comparing consoles to something that can do much more than play games. From word processing, easy internet searching/browsing (have fun searching the net on your controllers, yes I'm also aware you can plug in keyboards, but lol at that anyway), video creating/editing, artsy people using photoshop and other related tools, and so much more.
And honestly, there's far more reasons I could probably list but the point is there. It's a stupid thing to compare. If you like console gaming, more power to you. There's quite a few titles that aren't released on PC that I enjoy on consoles. I hate the controls, but hey, I enjoy the games so it's worth it. I prefer PC gaming more for everything else because A: it looks better and B: the other 90% of games I play are on PC and consoles both, or just PC only. Try playing games like SC2 on a console controller.
