Welcome to Tom's Hardware Forums,
Although I could give you some helpful advice here, I will instead direct you here. Read this thread and consider the questions it asks http://www.tomshardware.com/forum/353572-31-build-upgrade-advice
then post your build question in this section http://www.tomshardware.com/forum/forum-31.html
There, you will find many more people (than in this section) willing to give build and parts advice. Also, using the format from the first link does help a lot for us.
Good luck
