GeForce GTX 560 vs Radeon HD 6950
Intro
The GeForce GTX 560 has a core clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 6950, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this specific card. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling 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 the video card can 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of 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.

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.
