The GeForce GTX 770 Review: Calling In A Hit On Radeon HD 7970?
Wait, the new GeForce GTX 770 is powered by Nvidia's old GK104? That's right. And guess what? The card is faster, quieter, more feature-complete, and less expensive than the GeForce GTX 680 that came before it. Can it usurp the compelling Radeon HD 7970?

The cooler shroud is made entirely of plastic, which contributes to the cards lower weight. Two metal decals suggest higher-quality materials, though. The fan design carries over from previous Jetstream cards. A big 92 mm fan sits in the middle, flanked by two 80 mm blowers that are bigger than any on the Gigabyte card.
Palit equips the Jetstream with one eight- and one six-pin power connector. The gap between the two indicates the company may originally have had other plans.
Two 8 mm and three 6 mm nickel-plated pipes made of sintered material draw heat away from the GPU and into the bifid sink. RAM and VRMs receive their own cooling courtesy of a massive frame that gets sufficient air flow and helps stabilize the PCB.
Palit‘s GTX 770 OC Jetstream also carries the same complement of connectors as Nvidia’s reference card.
