so how do u overclock your video card ????
I have a GTX 560 Ti....
There are plenty of utilities around for overclocking.
MSI's Afterburner and
EVGA's Precision come to mind. Depending on what brand of card you are using then it may come bundled with OC'ing/tuning software (Gigabyte's OC Guru, Asus's GPU Tweak, Palit's vTune etc.)
For the purposes of simplicity I suggest you look at MSI's Afterburner. Check this post:

Two things to note:
If your card isn't an MSI, you may have to enable unofficial overclocking. So once downloaded and installed, go to:
C:\Program Files (x86)\MSI Afterburner and edit the MSIAfterburner.cfg file with notepad or notepad++
Find "Find UnofficialOverclockingEULA" and add
I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
And immediately below it, Set "Set UnofficialOverclockingMode" to
1 (usually is set to
0)
Use the included MSI Kombuster ( a FurMark derivative) for stress testing, or a selection of GPU+VRAM intensive games. Overclocking is an exercise in patience as much as anything else, so small 10MHz (initially) and 5MHz (once the overclock starts building) is definitely the way to go....and of course, when trying to find a stable overclock you should be only increasing core
or memory until you've reached a satisfactory OC. I would recommend going with overclocking the core (shaders are bound to the core speed at a ratio of 2:1) for most noticeable results, then look at memory overclocking- although this is likely to being minimal gains in comparison.
Keep a very close eye on temperatures .Afterburner, Precision etc offer real time GPU temps and the ability for you to choose a custom fan speed profile- I would also strongly recommend having
GPU-Z running (click the "sensors" tab)
