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.
ok, im getting this gpu now because im just waiting for the next gen of cards, i hear will come out between dec - feb. im getting a 3930k because i will be getting this build for a little over 50% of the current price, which will put me well within my budget
the thing is... i need to begin editing videos soon and my computer can barely open sony vegas, and i cant even put a video in it without having it freeze on me because of the little power in my current computer. i was just thinking on waiting on the gpu, im video editing mostly for now. and then if i want to i can upgrade with ivy bridge-e when it comes out
Well if you need it right now Then I would try to scrape a little more money together. You could try getting a cheaper cpu or motherboard. Also you don't need a 1200w psu for this build. You don't need that much power unless you have two 480's or 3-4 gpus. And if you really can't, then I would get a 7750 or 650.
You should seriously actually name what GPU you are talking about. I'm talking about. Are you talking the upcoming Nvidia 7xx or current 6xx series? Or the AMD 6xxx and 7xxx and forgetting a digit? It's really confusing.
It wouldn't be a bad idea to get a 660 right now then sli another one in a few months.
Also if you are thinking of getting a 660ti don't, and then get a 7950 instead. The 660ti is not good for the price at all. As a matter of fact tomshardware was able to get a 660 to almost as powerful as a 660ti with overclocking.
