670 WF3 is still a good deal with ~ GTX680 performance for $100 less. NV cards also tend to have slightly higher resale values from my experience, at least in Toronto/Canada. Don't sweat it too much. An overclocked WF3 670 is very fast for 1080P. No matter what you buy, eventually something will be cheaper and/or faster. Hard to time it perfectly. Just enjoy your GTX670 WF3 before GTX780/HD8000 series launch and make our current cards look mid-range next year.
