Building a PC

How about 2 monitors for it?

It would leave bezels directly in the middle of your game. If you're okay with that, you might be able to pull it off.

But you are failing to see the hard proof. The proof is (as I linked in my post) that at 5760x1080, the SLI Titan only gets about 6-10 FPS more than SLI 780. Show me a benchmark where this isn't true, please. Because I showed you mine where it is. Are you saying 10 more FPS is worth 700 more dollars, forget "potential", show proof.

Metro - 5760x1080

SLI 780 = 52 FPS

SLI Titan = 59 FPS

 

Battlefield 3 - 5760x1080

SLI 780 = 61 FPS

SLI Titan = 67 FPS

 

FarCry 3 - 5760x1080p

SLI 780 = 59 FPS

SLI Titan = 64 FPS

Seems like your logic isn't working out with real-world results.

Bioshock Infinite is a game that can benefit from having extra VRAM. 1GB is not enough for 1080p so logically 3GBs won't be enough for 3x1080p.
