Is there any problem in this cpu i7 870 ?

Yes that CPU is fine for that socket however it depends on what you are using your computer for. That CPU is most likely not suited to your needs and something such as a i5 750 would be better. But obviously I cannot comment on it until you say what you are using it for.

thanks alot guys I will do every thing I am a programmer, gamer and trying to do 3D modeling too as a hobby  

after I saw the 870 price I will not get it of course

The i7 860 or i5 750 are much better options.
