GeForce GTX 560 vs Radeon HD 6450 (OEM) 1GB
Intro
The GeForce GTX 560 features a GPU core speed of 810 MHz, and the 1024 MB of GDDR5 memory is set to run at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which uses a 40 nm design. ATi has clocked the core speed at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this particular model. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

Is 320€uros worth buying a new, not used, Asus Gtx560 1gb gddr5? im thinking its a bit much. if u dont know which type of 560 im talking its the one that has the horse image on its package.
