The GeForce GTX 770 can best be described as a GeForce GTX 680 with a slight overclock (up 40 MHz to 1046 MHz) and a more notable boost (up 250 MHz to 1752 MHz). Introduced at a compelling $400, the 770 doesn't sport an exciting new GPU, but it's certainly a value leader compared to AMD's Radeon HD 7970 GHz Edition, which tends to cost $40 to $50 more.
At that price, the refreshed GK104-based board earns our recommendation.
In comparison, the GeForce GTX 780 is a de-tuned Titan with two of its SMXes disabled.
The GPU still wields 2304 CUDA cores, though. In the process of slimming GK110 down, Nvidia axes the chip's advanced FP64 capabilities, dropping back to 1/24 of the FP32 rate.
Gamers won't really care, though.
On the plus side, GeForce GTX 780 costs $350 less than Titan.
Even still, this $650 board is too expensive to garner any sort of value-oriented recommendation. It is an interesting option for builders looking to cram lots of performance into a small place with modest power use.
Nvidia is also getting more aggressive with the pricing on some of its existing products, particularly the GeForce GTX 670, which is down $20 to $350.
The GeForce GTX 680 dropped $30 to $420, but with GeForce GTX 770 selling for less, informed gamers won't be touching that one.
On a side note, GeForce GTX 690 and Titan are both tough to find, with single models going in and out of stock on Newegg.
As far as AMD's products go, we're seeing $10 drops on the Radeon HD 7970, 7950 Boost, 7870 2 GB, 7850 1 GB, and 7790.
Unfortunately, none of those adjustments take those models close enough to competing GeForce models.
In addition, we're surprised to see the average price of low end Radeon HD 6450, 6570, and 6670 DDR3 cards increase about $10.
