Another factor would be that i don't play many AAA games now, due to the BS that comes with it. A lot of consumers are disillusioned with the AAA market just now. You could say it's mostly this market that drives the sales of GPU's as these titles need the grunt to run them properly. If the AAA market continues to be a ****show, it could effect sales of GPU's in the long term.
I'm not willing to play a long with this blatant overpricing of PC components, so I'm now investing far more of my time in consoles
This is a huge concern as well. It's definitely driving some away from the PC market. Regarding consoles, i thought about going back once the next gen systems come out. But in reality, this isn't going to happen. Mainly because:
1) i like all my games to run at high frames rates. Even next gen consoles won't offer this as it's always been image quality over frame rate for these systems.
2) I hate physical media and value space in my house more. Going digital only on consoles is extortionate, it's not even an option, plus i'm mainly stuck buying my games at one store (PSN/Microsoft Store/Eshop), etc). On PC, there are multiple online shops where i can buy games. It's hugely competitive, which is great. Also being able to refund your digital purchases is a big deal, on consoles i know Sony/Nintendo don't offer it.
3) On PC backwards compatibility is unparalleled.
4) I've got over 400 games on PC. I'd need to start my library over again if i went back to consoles. Plus it would cost more (as stated in my second point).
5) I'm not convinced of the longevity of PSN/Xbox/Eshop. Going all digital on consoles is a huge risk. Nintendo are notorious for closing services down i.e. DS store, Wii Store, Miiverse, it's only a matter of time when they close the Wii U/3DS stores. Also, the PlayStation brand is the only thing that's keeping Sony afloat (oh that and their insurance market). Microsoft aren't any better and wouldn't think twice of stopping a service at the flick of a switch i.e. GFWL.
On PC, my purchases feel safer and if anything did shutdown, i could download my games through other means.
So aye, weighing up the pros and cons of each platforms, i came to the conclusion that consoles are obsolete purchases from a personal standpoint.
PC components are at a higher cost than everybody would like just now. But, i honestly believe in the years to come that'll change for the better and components will get cheaper.
