GeForce GTX 660 vs GeForce GTX 660 Ti
Intro
The GeForce GTX 660 comes with a core clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 192-bit bus, and uses a 28 nm design. It is made up of 960 SPUs, 80 TAUs, and 24 ROPs.Compare all that to the GeForce GTX 660 Ti, which has GPU clock speed of 915 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 192-bit bus. It also is made up of 1344 SPUs, 112 TAUs, and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.

GTX 660 costs about 200$+ and is just about 30-40% slover than a GTX 670 which cost 400$...
You will not see difference if you don't have problems with FPS...
if we want to use ATi radeon 7870 we need amd motherboard cause this card has crossfire technology which is you can only use on amd motherboards
in this video he have intel motherboard so u are wrong u can install this card on intel motherboard
so prefer 660 Ti if there is no problum of money
Don't talk about what you do or do not know when you can't even speak english. Get a life and don't go dissing other people MR "Better than you guys" You seem like a tosspot nub.
The 660 TI was just out of my price range, at $230, plus $15 shipping.
Both cards have similar performance, and I'd rather spend the extra $85 towards an SSD.
It just depends on what kind of deals you can get, and of course I'm limited by my 460 watt power supply until I can upgrade it.
