Theoretically speaking, the Geforce GTX 760 should be 253% faster than the GeForce GT 340 1GB in general, due to its greater data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 137856 (253%)

Texel Rate

The Geforce GTX 760 will be a lot (more or less 435%) faster with regards to AF than the GeForce GT 340 1GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 76480 (435%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 760 is a better choice, by a large margin. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 26960 (613%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
