Any reason why you aren't going with a Z77 board? I haven't heard of issues like boot loops or SATA ports eventually dying like I've heard with the first-gen Sandy Bridge chipsets. Besides, you'd first probably need a BIOS update on that P67 board to get it to work with the Ivy Bridge chips.
I already have the board. I got it from a friend who RMA'd it to Intel due to the SATA bug. I'm pretty sure they updated the BIOS. While he waited to get it back, he got impatient and bought a newer board and CPU. I've also got 4x4gb DDR3 DIMMs, I think they're Crucial Ballistix.
I'd be re-using my Galaxy GTX460GC 768, my drives, my sound card and my Season S12-II 500.
My usage is mostly general use, watching HD content and gaming on Windows 7 x64.
My primary monitor is 1680x1050. Games I'm wanting to play maxed out at this res are Bioshock Infinite, Crysis 3, Metro Last Light, Max Payne 3, and Tomb Raider w/hair effects enabled, Watch_Dogs, Black Flag and Call of Duty Ghosts (SP).
No, I'm not upgrading my monitor. I'm also not going to sell my current parts, because they're worth maybe $30 at most, and more valuable to me as a new HTPC.
