Which one?

Here's the system I'm planning on building (first rig ever for me):

Intel Q6600
HD4870 (Planning on crossfiring another later)
Seagate 500GB 7200 RPM 32MB
G.SKILL 2GB 240-Pin (x2)
RX-700SS ATX PSU


I'm looking at two motherboards right now --

Which one is the best for my situation? (Or is there one that will beast them both?)

Oh, and haha, what do you guys think of the build in general? Will everything work?

well are you planning to overclock it? personaly i would take the ASUS out of the 2.
