Hi, I've considered overclocking my GPU with Asus SmartDoctor!. i was just wondering what the difference between overclocking the Shader, The engine and the memory is, and what is the best thing to do if you want overclock It ? (I've got an Asus Nvidia GeForce EN9800 GTX 512 mb DDR3 GPU) Beforehand thanks :)

In simple terms, the three are all parts of the architectural pieces that make up a video card, In reality, a video card is really a complex PCB. If you want to delve deeper into "how complex" there are lots of materials on the internet dedicated to the subject. The *Shader* is a program (set of instructions) executed on the (GPU) graphics processing unit for rendering purposes. It used be normal for a video card to have an non-unified pixel & vertex shader pipelines for rendering calculations. With the news cards including your 9800GTX, what is now employed is called a unified architecture where no pipe is specific to one task. The *Core* has to do with the GPU's clock speed & the *Memory* likewise has to do with the GPU's memory clock speed. With your 9800 GTX, you should be able to net a stable performance gain of about 15% with the three overclocked. The default Core/Memory/Shader on the GeForce 9800GTX are 675MHz/800MHz/1688MHz respectively. You should be able to easily crank those to 850MHz/1250MHz/2150MHz!
