Saris,
Here is a link to the generic system that I've built mine, and both of my son's PC's from. The list changes a little over time, because I update it with newer pieces as I know new pieces go to market. I never really buy top of the line, but mostly items that have just been replaced on the market with the newer item. So I'm never paying top dollar for the most recent hardware. This is not quite the $3k set up that Kyle suggested, but it likely would be if I included a 4k monitor. As Oleander stated, the 1000W Power supply is a little overkill, but I do like to buy the platinum rated and I don't like putting the load on my system that causes it to be close maxing out the available power. I generally like to put a little extra $ into my power supply because I do tend to buy SLI capable hardware and thus I will not be approaching the max power even with the addition of a 2nd video card. You can sometimes get a "video upgrade" by buying a cheaper older match to your original and running SLI rather than buying the new video card releases. That can last you until you're comfortable buying into the new video card release. This is also contingent on whether you want a bluray drive and/or whether you want to buy a Microsoft license and install via bootable USB. The setup also does not take into account your other preferences for accessories, like keyboard/mouse combo's, etc.

I also normally use pcpartpicker to build the system and check compatibility and power requirements, but then normally replace the pricing with my local MicroCenter store prices, which gives me the comfort of driving and returning items rather than relying on the delay of shipping and the annoyance of damage in shipping. So the prices here may vary +/- $20.00 here and there.
