OK I reverted my purchase back to the BIOSTAR TZ77B LGA 1155. I guess it makes more sense to spend a few extra bucks to upgrade my mother board to a Z77 than it does to downgrade my processor to a non 2500K.
Unless something has changed, you can't overclock with an HXX motherboard. Really limits possible performance. Either skip the K if you really have no interest in getting 20-30% free performance, or get a ZXX board.
Barracuda Greens are pretty terrible drives too. If you have a backup, it's nothing to fret over. But if you are relying on it as a "safe" drive to store media on, I'd worry a bit. To each their own on that though.
I also switched the Barracuda Green 1.5TB harddrive to a Barracuda (Non green) 1TB harddrive. Which was similarly priced.
From what I can see, the greens are mostly unreliable. And the standard Barracuda line is OK.
