ADDITIONAL COMMENTS: I'm just using this as layout so I would know what to but when the time comes. I also know some of these prices might change during the duration of when I might buy the parts. Some parts are the same. And I'm not sure about the USB 3.0 and SATA 6gbs. And with each one, I want to make sure I don't need to make an major upgrades within 1.5 years.

^ IMO both are very good for your needs...but the i5 750 would be faster than the 955...
And some mobo options to reduce the cost...
GIGABYTE GA-P55A-UD3 - As your wont be doing Crossfire, this mobo will do...

But then again do post when you buy the components as things will certainly change...
