I am not sure I am following you. I think you agree with what I am saying about half assing PCs since you lose the benefits of PCs and don't have the benefits of consoles. But you also seem to be suggesting that an alternative would be a steam console that has the GPU power of two titans in SLI? Or are you referring to a "stream" box like say PSnow but with the GPU power of SLI titans....

Either way, both scenarios won't work.

1. Steam console with GPU power equivalent to 2 titans in SLI. Too expensive for one, you will be looking at a console that will cost at least over $1000. Just not gonna happen. Now even if said box is upgradeable, it brings us right back to the problem of a lack of standardization thet plauges the PC today. If you want to standardize the hardware, then you basically have a console that is too expensive and that has limited support for a fixed range of hardware parts that would unfortunately be sold at a premium.
2. Stream console with 2xTitan equivalent power. Again, not possible. People talk up a lot about streaming games but fail to understand how that really works. Game streaming basically means that the console is not in your living room but make no mistake... its somewhere. If you want the stream box to have native support for say a HD8350 cpu + HD7970gpu (lets call this setup SB1)  all the devs making games will have devkits that basically have SB1 chips in them and  then you will literally have to have an SB1 for every single user that signs up for your service. So basically, if 50M people spend teh $99 for the reciver and controller that will be in your living room, then you will have to have 50M SB1s in your server rack somewhere. The amount of money it would cost whoever does this will be absolutely ridiculous. If they were charging $20/month for the service, it will take them 4 years to break even. PER USER.

consoles have become pointless, since they're using the same architecture as a pc, and they're basically all about software updates and downloads nowadays, I don't see what's the point of them anymore, they Have become a poor man's pc,

You can argue they're cheaper but so are PCS, you can get a better pc for the same price and upgrade it from there, and that will last you till your motherboard explodes (forever), you get cheaper games, more functionality, more room for tweaking and more ways to play, also free online and unrestricted services.

Look I'm not saying this as a pc gamer I'm saying this as a fellow gamer, handhelds have buttons over phones, consoles have nothing over PCS so what's the point of them nowadays? In the old days it made a lot more sense, consoles were meant to be "plug in and play" experience as in you buy a game from the store and you stick it on the console and play, now you buy it off the store and install it, and then download the patch and hope everything works fine, what difference is there from a PC? I would love to hear what you think the difference is. 

Now developers are always talking about graphics and how much 1080p 60 fps their game is, it's like you bought a console so you can argue about specs on the Internet instead of playing it,  and then comes ps5 with PS4 games with updated graphics "how it's meant to be played" crap by developers,  and the sad thing people always get sucked into that pr bullshit, I could argue for a long time but tell me, whats so different about a PS4 and a PC? 

Yea about when they are 70% off on Steam, sales on consoles are bigger just look at Minecraft and how some games are released later to avoid piracy.

Shhh. Dont say these number loudly. It will make anti console guys upset.
