The 685 isn't a thing. What is is your computer for? How m video editing will you be doing? If I were you I would either wait to be able to buy that new card, or see if you can scrape together the money now. Honestly the most expensive cpu I think you should get is an i7 3770k, that will do anything for editing, also you will have no increase in gaming over an i5. If you follow my suggestions the will save you hundreds of dollars, and enough to have a new gpu.
