Thats the parts im planing on getting still debating on the HD Radeon 7850 but as for the motherboard I was wondering about what would best suit my build? Atm ive checked out:

ASRock Z68 Extreme3 Gen3 ATX LGA1155 Motherboard <- first choice when i looked around

ASRock Z77 Extreme4 LGA 1155 Intel Z77 <- worth the upgrade?

MSI Z77A-G43 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS <- this was suggested to me

I was wonder like the pros/cons of each mobo maybe and how one is better than the other or how the BIOS screen help etc. Anything and everything will help :).

Give me some suggestions I plan to OC the CPU as well but maybe an option for SLI or Xfire but thats in future. Thanks again
