Which Motherboard to choose? (ATX)

Hi

I am building a budget pc for the following use

* It will be mainly used as an Office PC in a Home/ Office/ Shop setup
* There could be occasional gaming (no 3D) or movie/ video watching
* No overclocking
* Should be durable in a non-AC environment

I am thinking of going with either the E2160 or E4500 C2D

I am considering P35 or G33 or G31. i am not sure which one is good for the budget and the purpose.

These are the motherboards I have in mind. Please suggest any good option other than the following also:

- Abit IP35-E
- Intel DG33FB
- Intel DP35DP
- Asus P5KPL-C
- Asus P5KPL-E

Can you please help me with a good suggestion?

Thanks.....
