[QUOTE=dazman76;351162]I know you mean well Smoochy, but this is the exact opposite of what a console is
Let’s take an example - the next XBOX ships with a GTX700. You then buy a GTX1400 (twice the poweh), and slot it in. How do you expect a game to take advantage of it? Console games have limited (or no) graphical options - they are specifically tailored and balanced for the common hardware supplied with the console. For the game to take advantage of your GTX1400, it would need to detect graphics cards, and customise levels based on the result. Do you see where we’re going? This is the start of the “PC problem”, and the more you try to support the higher hardware, the more of a mess you can create.
Also, you know for sure that publishers will say “well you can upgrade even to a GTX1800 - so let’s get screenshots on one of those, it’ll look sexy” - and then your standard, un-modded console owner with his poor little GTX700 is wondering why he spent £500 GBP on his console to get something that doesn’t match the box graphics 
You absolutely cannot allow console owners to modify major components - it becomes a PC title with lots of options and lots of potential for problems, and that’s exactly what a console attempts to avoid. Better to say, a console is all about providing a level playing field for each and every owner.[/QUOTE]
While mostly true the console could allow only a certain range of approved graphics card (low, medium, awesome) and then developers would simply need to code for the allowed cards. Maybe they just allow different resolutions or have more memory / GPUs allowing for faster processing and less “popping”.
But in reality a console is meant to work “as advertised” straight out of the box with no fiddling. That, and the console companies make the most money on software so they don’t want to be buggering around with more hardware. IIRC some consoles were sold at a loss or break-even price just to get into the market because the money is made on the games (and nowadays the subscriptions and microtrasaction purchases and DLCs).
