Hi sir, there is the recommendation I would like to submit to you for your new build.
With the new price adjustment that Intel have done (i3 and new i5 going out), the i5 750 is really well priced and offer a great performance/price ratio.
Maybe that could be an idea.
But if you want to really go with the i7 built the 920 is still applicable, but with a Asrock motherboard:

For the price difference, it sound better!

Now for the psu, depend on all your need, tell us more!
