I am upgrading my GPU soon and am wondering would it be worth getting 2 780's or just the one card? I'm running on 3 monitor setup and am looking to run next gen games on high settings. I have an i7 4770k OC to 4.4Ghz also.

What card do you have now?
And also if your going to have triple monitor setup your going to want a lot of VRAM.

I have vtx radeon 7950 HD 3GB I'm not getting what I want at the moment. Like if I want sli with the 2 cards I'd be 6GB? That should be enough ya?

It would be Crossfire and no it wouldn't be 6GB, only 3.

No crossfire/SLI doesn't scale the vram. So if you crossfired two 3gb cards you'd still have 3gb.

Well, if you can afford it and your willing to spend the money, getting two 780's would beat just about anything. I'd look at benchmarks though and see if you'd be able to get the performance you want out of two 7970's. It would save you a lot of money.

So would the sli 780s not be good enough to run next gen games on the 3 monitors?

I'm willing to spend the money alright so I think ill get the 2 780 cards. I have corsair hx 750 psu too. Will I have to upgrade?

Probably yeah. I'm not really sure how much power you would need though. I would look around on the internet and definitely ask around on the forums under power supplies. That overclocked i7 Should be compensated for too. That could use quite a bit of power under load.

Ya I was gonna get and 850 if not 1000 watt supply hopefully the cheaper of the 2 specially dropping the money on the 2 780 cards.

I'm just guessing but for that setup you probably would need something along the lines of 1100 watts. I would strongly recommend you ask on another thread on tom's. You don't want to mess up your rig with too small of a power supply.

If next gen gaming at 5760x1080 is your primary concern, you may want to hold out a bit longer on making an upgrade. Crysis 3 is the closest thing we have to a next gen title, and it requires THREE 780s to be smooth at that resolution at maximum settings.


Good point, but now that consoles are switching to PC architecture hopefully ports will be much better optimized and there's a good chance next gen games might run better on existing hardware.

I dunno... Crysis 3 looks fairly indicative to me of what's coming down the pipe...


That's very similar to Crysis 3's performance (yes, I know it's alpha).


Looks fairly promising, you can't really predict the future though. The next gen consoles will use x86 PC architecture. So ports will be optimised better for PC.

Titans have more Vram, better for stereo displays, or 2k+ resolutions. the 780 being 3gb i wouldn't go past 1 card for 1080p/60fps , but if you do game at 120/144 fps i would say 2 780s in sli would be your better choice, still would go for the titan in stereo/2k+ resolution. the 780 really struggles giving you 100+fps on good settings. go sli to get some godly 144fps gaming!
