The thing is that as folk get into gaming PCs they seem to get on an upgrade treadmill. Next thing you know they are getting UltraWide displays and dual Titans. Video link to follow.
That's 2+ Grand just in video cards. It keeps up until you decide it didn't.

Since next gen consoles are coming out, I believe this is the perfect time to go PC. I'm looking into getting this card: http://www.superbiiz.com/detail.php?p=AT-7850_2G&c=pw&hash=e4dfEGmIoRJwBzccVGOJSaLTybilxmQ7Y7R8MXkZYhHqJUzfT%2B9pZGQyUc8iktW2XanCdadgn%2BhORoxyW8DgZJcSQWIZeRmzV5ATcCcVA7EJs4aisAcm3yCXDEip
And I was wondering how many years should that card and an i5 3570k be able to keep up with modern games?
