If building a new rig rather than upgrading, I wouldn't invest in "end-of-life" socket 1155 components.
If replacing a dead MoBo.... act fast....Z77 boards are going outta stock on newegg daily. Again, hesitating to invest $$ ina dead platform, Id get the ASUS P8Z77-V LX for $120 .... after $10 MIR .... Im 3 for 3 at 4.6 w/ it
