I would recommend you :
If you aren't in for the NEWESt video games, i advice the Asus P5N - MX, Wich costs in belgium around €40, Has SATA, PCI - E 1.0 , S775, DDR2 (2 - slots ) .. Its very small so really not the gaming motherboard..
If you want better stuff, try the Asus P5QL , wich has PCI 2.0 and is of course faster than the other , 1.0 motherboard...
Price is around 70- 90 Euro's for this thing ..
Now if your from antwerpen or so... I would advise to take a look at
www.drac.be .. Its cheaper than the overall prizes.. Just Pm me if you want to know more about the information i just gave you, i can detail it better or give other suggestions.
