Motherboards Advice

Hello Everyone.

I will be buying a pc for office purpose. I am more of an Intel guy than AMD. I am focussing right now on -

-Intel Core 2 DUO (E7300 or E8400)
-2 GB RAM
-Will use motherboard's inbuilt Graphics & Sound
-SATA Hard drive
-Windows XP

I need advice from you guys as to which motherboard should I go for. I mean i dont want to go for a cheap board and ruin my pc's performance.

I dunno if this is true or not but are intel original motherboards better than chipsets (like mercury, asus, gigabyte etc).

I was thinking of going for Intel DG31PR motherboard. It costs around $65 here. Some people say motherboards from companies like Gigabyte or Asus are better. For example a Gigabyte G31 motherboard would cost $50 or so. And will provide better performance. I dunno if this is true or not. Are intel original boards better than other companie's boards. What do you guys say ? What should I guy ?

Thank You,

JG
