That's a lot of MoBo for your stated usage. You could easily get by with the P8P67-Mhttp://www.newegg.com/Product/Product.aspx?Item=N82E16813131708
For the "top of the line" the Deluxe is a great board but if gaming is a priority, just $20 more gets you the Asus WS Revolution which gives wider bandwidth for hi end GFX cards.
You can get in a combo with the CPU here
$555 w/ i7-2600k http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.660789
$465 w/ i5-2500k http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.660792
I'd get the 2600 only if tackling workstation type apps that take advantage of hyperthreading such as Photo / video editing, large databases, 3D rendering etc.
