Why don't the people that are posted in the OP each make suggestions for a build and work on it together so we can compile a list?
Takes too long, price tiers become muddled if different people do different ones because of personal preference (more gpu power, etc)
What we should do is have one person submit all the starting suggestions, then everyone critiques. The only problem is that I've done that twice now and nobody bothers to critique it.
yes, the z87 chipset is newer than x79, plus youll be able to have the next-gen broadwell line of cpus in a few years
Well, technically it's newer but that doesn't make a difference. First of all, nobody is going to change from haswell to broadwell unless they're rich as forget, there aren't going to enough significant changes to justify it. And if they're rich as forget, chances are they have X79 mobo because they have an i7-4970X
x79 is only for extreme edition CPUs and it only has the 2011 socket.
This. On the subject of actually getting the 4820k, it's really not worth it. If you have ~$350 to blow on a cpu, get a 4770k or 3770k + an aftermarket cooler. Unless you know for a fact that you'll benefit from having 12 logical processor cores, Ivy Bridge-E simply isn't worth what you're paying for
