A benefit of a console over a PC is the titles being developed to run optimally on specific hardware. For the next 5-6 years (or longer), you can safely assume, with few exceptions, the PS4 will run all games lag-free (graphical lag, that is). Assuming the PS4 has a similar price to the PS3 (personally, I expect a lower cost), a $600 PC purchased today, will not meet the minimum requirements for mainstream titles for the next 5-6 years. WoW is not a benchmark game. WoW is specifically designed to run on minimal hardware. One of the key marketing points of WoW has always been to make the game available to as wide an audience as possible. That's a Blizzard thing; notice they did the same with Diablo III. Crysis has always been a bit extreme with graphics. How about we settle on something that has good middle-of-the-line graphics, such as Skyrim? If I purchased a $600 PC 5 years before Skyrim came out, I wouldn't hold my breath hoping to run it smoothly at 720p, even on low graphics.
Outside of digital content, or requiring multiple discs per game, the Xbox 360 couldn't run games near the graphics of a PC because of the limited disc space.
I want to see specs to see what it would cost to actually build a pc better. Just like my post.
YES----I would be willing to pay more for the system that would play the new & old games.....even though I currently own 2 PS3s and a PS2 system. I have huge libraries for both systems....I never get rid of games! The newer systems typically run better/faster....so it would be nice to play some of my current/old favorites on a better system. Plus, if one of my older systems die.....I don't have to worry about a replacement!
