Agreed. If you have the $3k for a titan z and some for the psu, you should rather go with a $300 z97 board, 16 gb of 2400 ram for $200 (->$500), two 780 ti's for 2x $700 = $1400 (->$1900), an I7 4790k for $300 (->$2200) and a tier a quality 1000W+ psu for $200. Then you're at $2400. Add a noctua nh-d15 ($100) to it and you're still $500 cheaper than for just the titan z. Optionally add in a 516GB SSD for $500 to get to a total of $3000. Now you're at a pc capable of running any game currently existing on 4k. Much, much stronger than with just one titan z.
