GeForce GTX 560 vs Radeon HD 6950
Intro
The GeForce GTX 560 features a GPU core clock speed of 810 MHz, and the 1024 MB of GDDR5 RAM runs at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.Compare all that to the Radeon HD 6950, which has a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

Why you should believe none of what you hear and only half of what you see: http://www.tomshardware.com/forum/307584-33-5870-6950-dont
Apparently, a Tom's H/W "Guru" predicted the 560 would be a superior card .. how'd that turn out??? What a load of fooey. People, do your own research & gather as much background on cards before committing to any particular model or brand.
