Hehehehe... well, with an EyeFinity HD 7970 Ghz, that would be awesome. Imagine 6x DisplayPort powering 3x 4K monitors, using 3x HD 7970 Ghz EyeFinity 6GB in CrossFire using an X79 with i7 3970X CPU. xD
Put the 3 monitors vertically, side by side. So 3 monitors in 3840 x 2160 becomes 6480 x 3840, in triple Portrait display setup.
Combo that with a 7.1 home theater surround sound speakers, using a studio-grade sound card, and specialized cables... and now you've got a recipe for uber-gaming.
I think that link I shared could be considered a "man cave-gasm" or a "tech-gasm" of "Sooo much power!".
(I think maybe PC gamers should share this link to console games, with one short line: "PC Gamer Master Race member. This is why. Any questions?" Hahahaha, sorry, sooo many jokes to make here.)
Yes we pc gods are far above the peasants fighting about whats better thpoplar station or the Xbox, we are the true gods of gaming and they shall kneel before our mighty gaming pc's.
Although, on a more serious note, PC has a lot of advantages over consoles. Being able to game in 4K is just one of them. Being able to choose from so many peripherals, getting more powerful components, F2P games, MMO games, etc.
Pretty much every exciting new technology is made on a PC first, and later moved to consoles. Even console games are first tested and run on computers, before they make their way onto the console - even if it's a console exclusive. Even XBox One-80 demos ran on PCs with Windows 7. I think that says a lot about PCs.
We all know Dirt3 isn't the most GPU intensive game out there, he could have gotten away with using probably just 1 really high overclocked 7970 with an overclocked CPU to run that resolution.
I hear that even using 3x HD 7970, when running at 12K resolution, he was only getting about 8fps on average! 0.0 That's because he was using max settings. Think of it this way; imagine running 4x 1080p monitors set up in a square, using a single GPU, running Dirt 3 at max resolution. Now imagine that's what's being done on 3 monitors, using 3 GPUs in CrossFire. Remember to add the latency and inefficiencies of CrossFire to the mix.
Then, add in how much VRAM is needed at 12K resolutions. Now you're starting to get into why his frame rate dropped like a stone in a lake.
