GeForce GTX 295 vs Geforce GTX 680
Intro
The GeForce GTX 295 has a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also uses a 448-bit memory bus, and uses a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 28 ROPs.Compare those specifications to the Geforce GTX 680, which has core speeds of 1006 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 TAUs 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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum 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.
