GeForce GTX 660 vs GeForce GTX 660 Ti
Intro
The GeForce GTX 660 uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this particular card. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.Compare that to the GeForce GTX 660 Ti, which features core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs along with 112 TAUs and 24 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max 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.
