I'm sorry that I am replying to this so late, I haven't been on these forums for quite a while, however the content of your comment has compelled me to reply.
For clarifications sake, I do not believe the 780ti at $700 represents 'maximum value for money' (nor indeed a 290x for a similar price), and I personally do not own nor have any intentions to purchase a 780ti. I simply believe that as the 780ti was at the time the most powerful video card available, a high price tag isn't particularly unreasonable.
I even suggested better value high end cards that were well within your budget and were still a huge upgrade on your 460, and yet I was greeted by a sarcastic and ignorant comment..... annoying.
