A few things u should know about SATA/USB 3.0 tech and mobos as shown by our very own forums here
USB 3.0, SATA 6Gb/s, Motherboards, And Overcoming Bottlenecks

Also note that LGA 1156 shall be usurped by LGA 1155 as soon as end of this year/possible Q1 next year if u intending to sink a wee bit on chip + board FYI...

At such low res i would think a GTS 250/HD 4850 and a Rana 440/445 would be more than adequate at a few hundreds cheaper @@
