Excellent mobo chip bundle for my grandson's first PC. When I upgrade mine I will use AWD-IT again.

Genuine support and fast response. Much appreciated
Pros: Does the jobCons: none
Item works well, is fast stable, Ex for gaming will buy more when others need upgrading.
this is a great starting/ budget motherboard, its got everything you need for a decent setup and its quite easy to connect components to plus it has a great layout!
Paired with an AMD 3100 and 16 gig of 3200mhz RAM it has proven to be fast loading and smooth in operation. Very good value for money.
