This. Unless you are in a place/area/country where you can't get in on some of these deals.It's hard to tell when you are buying used. All else equal the 7970 will beat the 670.
Considering you can get 7970's as low as $360 ($330AR) with 3 free games new, I wouldn't consider either of them good value.
ok, I Think I'm going to go with the 7970 asus top. the one u guys linked is way slower then the asus one and it's offer better performance then the xfx one.

This Sapphire card is less expensive and comes with a higher factory OC. http://www.newegg.com/Product/Produc...82E16814202008
The V6GT is not that great for what it costs. What CPU do you have and how far are you planning to overclock?
As for the additional case fan, what case do you have and what's the current case fan setup?
For that OC just get a Hyper 212 Evo (which should actually be just as good as V6GT). $30 on Amazon.
You linked the case fan again, not the case.
Here is a 1Ghz brand new HD7970 with a good cooler and 3 free games for $388 or a $390 1Ghz Gigabyte HD7970 Windforce 3x that also comes with 3 free games.
I don't see any reason to buy a used HD7970 Asus TOP card with some warranty gone, no free games and Asus TOP was never a good overclocker this generation.
As far as performance goes, a 1Ghz HD7970 now = GTX680, not GTX670:

If I were you, I'd just pick up an HD7950 and overclock it. Better deal than GTX670/680/7970. Then you have $90-100 saved towards your next GPU upgrade. An overclocked HD7950 is an amazing value right now and is not much behind an overclocked 7970.
As next generation games get more demanding, it's unlikely that a GTX680/7970 OC will be much faster than an HD7950 OC and when all 3 of these GPUs are too slow, you'll have $90-100 saved for upgrading.
