Thanks for the input -- I think I'll go ahead and stick with the x99 then.
Just curious, what's the benefit of the PSU you linked? More stable? Better quality? Actually looks like the one I had originally is on 30% off -- still worth swapping?
I'm primarily building this for my personal work (heavy game development / various software development projects) as well as bit of light gaming (should at least be able to play common games on decent settings). I'd like the option for a Hackintosh as well.
