GeForce GTX 295 vs Geforce GTX 680
Intro
The GeForce GTX 295 comes with a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit memory bus, and uses a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.Compare that to the Geforce GTX 680, which features a clock frequency of 1006 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

No it doesn't - this theoretical chart doesn't take internal SLI scaling efficiency of 295 in to account. In real world, 680 wipes the floor off 295.
The GTX 295 still performs impressively with current games, if you are ok with DX 10.
Also it comes quite close to the GTX 680's general performance in high resolutions. But keep in mind, that a 680 is a single graphic chip, that needs less power and has the overall way better performance than an older GTX 295.
WTF?
Theoretical BS.
here is realworld results:

Lol GTX 295 comes neck to neck with GTX 680...if someone doesn't"t have problem with Dx10 he can sli them and easily in 3D programs beats all GPUs except GTX 690....
in general until 2015-2016 would be really good....then you will be able to buy from series : 9xx and 10xx...
It took a while but you can now 3-way two 295's and dedicate the last half to Phys-X.
