i dont know a lot about gpus so here are some questions :

1) what does effective memory clock mean?can you see a big difference between 4800Mhz and 5600Mhz?

2) what is openGL?

3)what is DirectX?

4)what is stream processors?

5) if you have a mATX motherboard with onboard video card, what happens if you add a gpu?

1. Effective memory clock is the actual frequency of the VRAM. Say, for example the AMD HD 7970, which has GDDR5 memory: its base memory clock is 1375 MHz, but its effective memory clock is 5500 MHz.

There can be a difference between 4800Mhz and 5600Mhz, but it depends on the application.

2. OpenGL is a graphics API (application programming interface). This can be used on all operating systems. Look here for more in-depth info: http://en.wikipedia.org/wiki/OpenGL

3. DirectX is a graphics API (application programming interface). This can only be used on Windows operating systems. Look here for more in-depth info: http://en.wikipedia.org/wiki/DirectX

4. It's pretty complex. Stream processing in general: http://en.wikipedia.org/wiki/Stream_processing

Stream processing for GPUs: http://en.wikipedia.org/wiki/Graphics_processing_unit#S...

5. It means you can use the graphics card, and that will be the GPU you will use.
