Any of those MOBO's listed are fine, for the money I like the ASUS P8Z68-V PRO/GEN3. Great OC, reliability, options, etc. IF you want a higher OC I'd recommend the H100. Further, I am not a fanboy of OCZ PSU's - I prefer Corsair or SeaSonic. A 60GB SSD is really small, and at minimum IMO 128GB or larger; the Spinpoint F3 (1TB) is a reliable HDD any you'll need a HDD.
I know I didn't say it but later I would be buy a second 7870 (few months maybe)… I could go with a cheaper MB (around that 120-140 range) but as I have a bit more cash for a good MB that's why I was looking that those ones ..
On the SB/LGA 1155 just make sure the MOBO has at least 12 Phases to the CPU, this helps stabilize the CPU and in turn you typically get a lower vCore. The top (2) ASUS's listed are 12 Phase, the mATX (micro) Maximus IV GENE-Z/GEN3 (8 Phase) is about the best mATX LGA 1155 MOBO you can get -- if you like mATX.
