[citation][nom]cronik93[/nom]How about fill the gap between the GTX 470 and 480Really becuase the 5850 out performs the GTX470[/citation]
singly, they go back and forth, with the GTX470 a little faster on average. Dual card, the GTX470 beats down the 5850 like mad, and even gives the 5870 a good run for less money. In addition, nvidia has less troublesome drivers. While the bugs might be about even, the usability of the nvidia drivers is far better, and it recognizes dual cards far more easily.
I researched these two cards, the GTX470 and the Radeon 5850, for about 3 months before I finally bought a GTX470. I certainly wasn't wrong. I've got mine overclocked to 775 with no problems, giving almost the same performance as the GTX480. I plan on buying a second when I get the money together.
