Your Mobo seems overkill the USB 3.0 will be nice, but you dont need much of anything else unless you plan on having a million input devices and overclocking on a higher level. You could save money there. And then maybe kick your 6 gigs up to 8. Also, why not pay the extra 15 dollars and get the 950? Check out this ram too... 2 kits GSKILL.
Oh yeah, I always recommend the Corsiar H50 for cooling your psu. Cheap and amazing, it also is a million times easier if you install it while you do your build instead of later. Then you have to take everything out to mount the bracket..
