Just got the 770 a couple months ago on release. I used to be a x60 kind of guy but I decided to splurge a bit. To be honest there aren't that many games which fully strees these newer high end cards just yet.
Probably the 860 mid range. I am using a GTX 470 now and although I am tempted by the GTX 760 I know I am better off waiting until next gen since in reality I don't need a new video card right now. I may end up going to the next tier higher than a 860 depending on how next gen cards deal with next gen games.
I've already had my new computer for a year now and it's not slowing down anytime soon. It still feels brand new to me. I won't need an upgrade for at least 3 more years, and at that time, I'll probably just bypass it and play on medium settings for a while, then low for a while, then in 5 years build a new machine.
Don't lie to someone who trusts you. Don't trust someone who lies to you.
