780ti SLI as it has the VRAM for 3 monitors but also packs a bigger punch for games. But, f you are open to suggestions, you might want to look at two 290Xs as they can also give you on par performance for less but with 1GB more VRAM.

Considering 4790k. Does this sound like an adequate CPU?

Yes it is perfectly fine, two 780tis will not bottleneck

It went above 3 gb of vram, not 4, meaning FPS would drop, so there is an issue with VRAM? 6gbs wouldn't do the job either?

Even 2 6gb 780's might struggle at that resolution.


I don't believe that, 6GB VRAM can at least run 5 monitors if one monitor takes one GB.

Two 290Xs can get teh job done on par with the gtx 780tis but they have 4GB VRAM so you'll have 1GB of leeway if each monitor takes 1GB or VRAM

I heard the 290's were slower than 780 ti's though, hotter, and louder.

they aren't that far from it, it's about a 5-10% difference. If you get a non refernce card from Asus or MSI, it will probably perform the same as an Asus or MSI non-reference 780ti.

It depends on the game. Even @ 1080p Wachdogs(as poorly optimized as it is) can use 3.7Gb of vram(see this on my rig). Even BF4 on a single 1440p monitor will use ~1.5-2Gb of vram(depending on msaa settings), so if you are using 3 1440p monitors on surround you are tripling the amount of needed vram.

New games are requiring more vram. Even Wolfenstein will get close to 3Gb of vram usage @ 1080p. 3gb would be fine for a single 1440p monitor but I would hesitate to use that much with 3 running at either 7680x1440 or 2560x4320.

Well then the best option is the GTX Titan Z with 12GB VRAM

Titan Z is not really meant for gaming, it is meant for Animation studios, and designers

Only 6Gb of that is usable. It has 6Gb per gpu and like any SLI or Crossfire setup usable vram does not add. So while technically it does have 12Gb of vram only 6Gb is usable since the 2 sets of vram will mirror each other. Advertising it as a 12gb card is technically correct it's also misleading.

Id still say the GTX 780 6GB is the best for 1440P, or I guess we just dont have the reasonably priced graphics card to handle 4K at 60+ FPS

@bignastyid, I agree with you on 3 1440p monitors, but 4GB would be enough for it if he turned down AA settings wouldn't it. And even if he kept it on, two 780 6GBs would be able to handle it if each monitor was taking 2GBs each. Or, he could go with something like a 295x2 with 8GB or VRAM and it would still be in his ballpark as two 780tis cost $1400 and a single 295x2 would cost $1500.

Yes because it has 8GB of VRAM, isn't gonna cost you the price of a used car, and is basically the only other choice you have

I think I'll be using 780 6gb SLI for multimonitor, as it has the most VRAM available outside of titan. Do you guys think two 780 6gb's will be powerful enough for 60fps (as VRAM is not an issue at that point) on any game?

The 295x2 only has 4Gb of usable vram. 4Gb per gpu.

It comes pretty close to the R9 295x2 performance in gaming
