I vote that he skips the need for the quad 7970s.
4x7970 = 4x($380+$140 for blocks) = $2080
For this you need more PSU juice, More Rad Space (a Minimum of 4x120 in push and push/pull if you are OCing) and you gonna run in Quad fire bugs and issues.
3x780s = 3x($650+$140) = $2370
Nearly identical performance with less hassle (Tri Vs Quad and I will always go tri since they are much much of a headache), lower power requirements when OCed, Less cooling (3x120)
With the 780s you gonna stay within case budget and you gonna need a lower PSU (You gonna need a 1500watt to feed a 4930k and quad 7970s. While, A decent 1200watt will do fine for 3x780s with a 4930k).
He and I spoke at length about that tonight, actually.
The main draw of the 7970s is their compute, which is still better than a 780 if memory serves (and a TITAN, I think). This is important for his schoolwork / hobby stuff. My suggestion was that he waits a little longer to see what ultimately shows in AMD's next gen. Get one 7970 now, no blocks, get all other watercooling gear + 1 radiator, and start using his system as soon as the 4930k launches. Let October roll in, observe, and decide then which cards will best serve his needs. If it's all that and a bag of chips, cool, offload the 7970 and buy new gen + blocks. If it's not, or is just the bag of chips, buy up cheap used 7970s, blocks, and rock on.
Nvidia is most likely out, though. Their 600 and 700 series cards simply lose out to the 7900 series Radeons in the areas of work he'll be putting the most effort into.
In any case (haha, bad pun), the case itself is set in stone. He loves the flexibility and tt will last him through at least two generations of builds, supporting watercooling for basically anything he'll need in the next six to eight years.Edited by BBEG - 9/9/13 at 1:42am
