I would go for the 930 build. Just got done building mine, have it in a very non-aggressive 3.8 ghz overclock, I mostly use it for Photoshop and Lightroom.
Get a good batch and this chip is amazing. Plus, I've hit 6 gigs of ram with photoshop cs5 (i have 12), so thats another plus for the 1366...
I did a lot of research and ended up going with the venomous x. I ahve an x58 ud3r though, and needed all 6 ram slots, so the megahalems and noctua were out.
