Hi my name is Baris, im here to ask you guys about something that im not sure at.

*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)

That is only a hypothetical reason not to; it is widely regarded that more memory is better, and I see no proof in any graph that the Titan's bust size is a huge hindrance. Whether the memory bus can handle it completely or not, anything above 3 GB is still going to be quite better. Also, unless you are using a very expensive motherboard, the third GPU is going to have a minimal...

I really don't think the memory bus on the Titan's is capable of using 6GB, look at the 3GB 660ti for example, at higher resolutions its not capacity thats the issue its bus width. Plus, 3GB is more than plenty for 3x 1080p, look at all the 7970 users.

Also, unless you are using a very expensive motherboard, the third GPU is going to have a minimal effect; on a regular ATX, you will be running all three at x4, which is sub par. It is much more effective to run two Titans at x8.
Also, the Crossfire drivers are extremely buggy (as we all know), so unless he wants to run just a single GPU, Radeon should not be in the question.

Alrighty well just buy 2x 780 then. The difference between the two cards is less than 7%, its ludicrous to buy the Titan given the price difference. 6GB really isn't necessary, what did people do before the Titan came out? Use cards with less.

Your last argument is completely invalid. Essentially, what you've said is that we should all revert to 9800GTXs or whatever relatively primitive GPU that we had before. People have always "used cards with less", but that does NOT mean that you shouldn't buy the card with more.

Have you ever heard of planning ahead? I'm assuming that OP is not going to replace $2k worth of GPUs next year. The Titans will age much better, as they have more CUDA cores and more VRAM, and will beat the tri-780s due to the problems with electrical slots.

I'm not saying he should get 3x 780, 2x would suffice. $700 saved over the Titans? Identical performance and same longevity? Yes please.

I mean, if you are right, then people with AMD setups must be screwed running Eyefinity, they only have 3GB, totally worthless, cant run any game at all with that.

But the question was not 2x 780 or 2x Titan. The question was 3x 780 or 2x Titan. I was simply answering the question at hand, instead of creating more problems in trying to solve the current one. I never said a single thing about people with 7970s being screwed, nor did I even say that the 780s were insufficient; I did, in fact, say the opposite. Please review your facts, and stick the question(s) at hand. Thanks.

i just figure, 3 way sli doesnt normally scale as well, titan has more ram, crysis 3 running 3x 1080p monitors uses more than 3gb, so you may see a performance hit on the 780's in some games, not to mention future ones. Whoever said something about the memory bandwidth it wrong, titans have a lot more mem bandwidth that your system ram does when it spills over into it, which may happen on the 780's in some games at that res. http://www.tomshardware.com/reviews/crysis-3-performance-benchmark-gaming,3451-7.html look at the high detail bench here, the titan steps it up due to its larger frame buffer beating the 690 but not on medium which uses less vram.

İm leaning twords Titans because with the new consoles having alot Vram i think in the near future games will use more Vram and i dont want it to be a issue after spending that much money on video cards. i will still be happy to see your guys opinions. i still have a week to decide so i will search more and this communitys thaughts are very important and helpful. :)
