i am planning to build a new pc based on the following spec :

MOBO: GIGABYTE GA-EP31-DS3L
CPU : INTEL CORE 2 DUO 2.8GHZ (E7400)
GPU: GIGABYTE ATI RADEON HD4850 512MB DDR3

is there anthing wrong in this build or mayb some recommendation

Not really,
but I don't know the reasons for choosing this mobo.

I personally would go with a P35/P45 with ICH9® or ICH10® (ICH7 is pretty dated)
® - if you want a RAID system

Also this GIGABYTE vs ASUS power saving shit is pure marketing bullshit ... actually those motherboard suck more energy then e.g. MSI board with some clever power saving strategy ...
I say that, because I fell for the ASUS advertising and later discovered, that its complete bullshit

ONE example

costs roughly the same, but has all the latest technology
