I too had that card
Thats a Utter crap now. Mine Fried out last week.
If you can wait, its very good.
But beware of the Premium prices.
I would suggest you a GTX 670 over 680. (If you are getting now)
Performance difference is just 5%. Which isn't worth the price difference.
Overclocking will further make the Difference 2%
So GTX 670 is a better choice all the way.
But if you can wait, you'll be happy.
