I thought it was recommended to use Titans over the 780ti for 4K applications (especially gaming) because the increased memory bandwidth really comes into play here.
I would not go for 3 780 ti in SLI for 4k, at that point you're becoming graphics memory bottle-necked. basically, if you can't get playable frame-rates on two 780 ti, you're kinda stuck unless you upgrade to titans or next-gen GPUs
Just a quick question, I was wondering if dual sli on 780 ti's will be good enough for a 4k display for if I should strive for 3 sli.
If any of you need to know I would also be running an i7 4970k, 16gb of ddr3 1600 RAM, and running it on an Asus PB287Q 28.0" monitor.
Thanks in advanced!
780ti sli should be good enough for most games at 4k but you may have to tone down the settings eg No AA, etc..
3 of them should make things a bit faster if they work, even 4 of them should make things fly. The problem would be CPU and VRAM limiting the potential... I feel.
But if you are still in the planning stage, maybe get something with a bigger VRAM for future proofing.
