Hello,
As being a Gamer and Keen about upgrading and using latest games and software's, I think I can help you with it. But I want to ask you what sort of work are you willing to do? Because with you description you need a Military grade motherboard. I am eager to help because after my last upgrade (long time ago) I am at an end to see that sort of PC.
Eagerly waiting for your reply. Hope to see you soon.
Regards,
Arnab Ganguly
