More aboutbuild ready time builder thing good ill ordering thing today
I'd say you have a pretty decent build. I'm not an expert on Intel processors and some higher end features, so I'd wait for a few more replies, but you have my approval.
RAM: Changed to 8 GB, gamer will not utilize more than 8 GB (That's is if you are only going to game) SSD: Upgraded to 840 Evo 250 GB, Pro is really expensive and might as well get the Evo 250 GB for a little more GPU: Changed to GTX 780, single GPU is always recommended over multi, single has better driver optimization and less micro stutter. PSU: Changed to AX860, not sure where the original one came from, but this one is cheaper, higher wattage
