GeForce GTX 295 vs Geforce GTX 680
Intro
The GeForce GTX 295 features a clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.Compare those specifications to the Geforce GTX 680, which comes with GPU core speed of 1006 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

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 (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory 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.
