Theoretically speaking, the GeForce GTX 260 Core 216 is 289% faster than the GeForce GT 430 in general, because of its higher bandwidth. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 83088 (289%)

Texel Rate

The GeForce GTX 260 Core 216 is much (more or less 270%) better at AF than the GeForce GT 430. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 30272 (270%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 260 Core 216 is a better choice, by far. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 13328 (476%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
