If i put a new clip to my sequence it shows me a yellow render bar which actually means, i should regive it without bucking or any problems. But even if i put effects on that clip, or an adjusment layer, the render bar wont get red. And if i render the yellow one, with the full effects on the clip, its not able to play it without bucking. So first i wont get any red render bars, secondly even the yellow is not playing without bucking

But, with no details, I don't think anyone can give any real comments... Information FAQ http://forums.adobe.com/message/4200840
Can you share your computer system specs, Premiere version, footage source format? Do you have GPU acceleration enabled? There are many factors affecting playback smoothness. Does the sequence preset match the footage? Mismatched frame rates are problematic for instance.
