GPU Overclocking terms ?

[varunmehta11]

I'm a new Graphic card overclocker, going to overclock my XFX 8400GS 256MB using Nvidia System Tools 6.02.
I want to ask what's the role of Core clock, Memory Clock and Shader clock of the GPU in Gaming.
Actually , i want to know how significantly each of the three clock speeds would improve the gaming performance on Overclocking ?

you are not going to see much of a gain from that weak card.just try it for yourself 5mhz increase everytime until you get BSOD or freeze then back down the value you have increase before by 10Mhz.
