Is it possible today to build a PC that is not jut next-gen ready, but future proof for that entire gen? A decade ago the answer was always a resounding no, but nowadays I'm not sure it is.
Back when the 360 was made a top end 7900 GT took a total of about 50W to run (if my memory is correct). The 360 runs at about 170W total load the last I checked prior to the elite model. The reason this is important as I'm sure you will all know is the heat generated and the required form factor of a gaming console. Therefore there is going to be a limit to the total load a console can run on before it becomes either unsightly, too loud or too hot.
The issue is that nowadays a GTX 680 takes ~170W on its own. Therefore with engines like UE4 and Cryengine 3 recommending a GTX 680, will they be able to ask for anything more? At a push, maybe the next gen consoles will reach the performance of a GTX 680 with some technical wizardry, but if they don't, will PC users really need more then a GTX 680 (or amd equivalent) to be in the knowledge that they are next-gen future proof (just 1080p gaming)? Of course there may be improvements made for PC versions of games, but those sadly are few and far between. One reason I ask is that I currently have a GTX 560 Ti. If I was to add a second rather then upgrading the card, how long would that last me? If we consider that an 8800GT still is a capable gaming card, how long will the power house cards of today last?
