The GeForce GTX 480 is a lot (approximately 275%) better at anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 30800 (275%)

Pixel Rate

The GeForce GTX 480 is a lot (more or less 1100%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 30800 (1100%)

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 largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
