2x GTX Titan's v 3x GTX 780's on 3x1080p res.
Hi my name is Baris, im here to ask you guys about something that im not sure at.
here i will give you my system specs;
*i7 3930k OC'ed to 4.5Ghz +*
*Asus p9x79 Pro Motherboard*
*Corsair h100i Watercooler*
*Corsair 600T White case *
*Corsair AX1200i *
*16GB Corsair Platinum DDR3 2133 Mhz RAM (4x4) *
*2TB Western Digital Caviar Black HDD *
*240GB corsair Neutron series GTX SSD*
as you guys can tell theres something missing ''video card'' im going to be gaming in 3x @1080p monitors and i want a future proof video card(s) im planning on useing this system for a while witch one of these would be better for me;
2xGTX Titans or 3xGTX 780s
(my main concern is the 3gb frame buffer on gtx 780 s)
3x SLI does not work well...with your 3rd card expect 50% scaling or less :/, get 2 titans.Also less noise and power consumption.
You do start to loose scaling with every extra card, but I wouldn't say it doesn't work. A few points...there is no such thing as futureproofing, but if you do want to extend its useful life a bit of extra vram will assist with it. Personally I can't justify titan's price premium unless you have money that you have no use for and its burning a whole in your pocket. Rough pricing 2xtitan will be $2000, 3x780 will be $1800.
For me I would throw the idea of titan out the window (though I know others are willing to pay the extra will disagree). Honestly for 3x1080p I would go for 2x780 and try it out...if you find its not enough you could always throw a 3rd in down the road. If you are concerned more about the vram than the total gpu power another consideration would be 3x770 (there are 4gb versions) that you should be able to get for less than $500 each.
If you haven't read it yet:
I know its not an SLI review, but they are based on the same architecture, so scaling should be pretty much identical per card added. With that said you could have SLI 780 giving you approx 95% of the performance of SLI Titan and $700 in your pocket. Save that $700 and put it towards new graphics cards in a few years when the 3gb vram starts limiting you. Either way you will not be going wrong, but I personally would not be able to justify the added cost.
Tri SLi 680 / 780 for sure, will slightly out perform SLi titans for less $$$$$, obviously at this level power consumption is a non issure ;)
