With the build you have, I would suggest going for a single 780 so that you have an upgradeable computer in the future. The 760 SLI is faster, but will not necessarily make you happy, due to microstuttering, higher temperatures, noise, and power requirements. You also may wait a couple of weeks on drivers for new games, as it may not be configured for dual card systems.

I agree with most of what he said, but microstuttering is not an issue with SLI as it is with crossfire. Two Nvidia cards offer a smooth video experience. I've had the last 3 generations 580s, 680s, now 780s. Last time I saw microstutter was with 5850s three years ago.

I agree with KSHAM on this one.

A single graphics card setup takes less power, less heat, less space. Plus you wont run into the issue of microstuttering or other errors that SLI can bring. Some games don't even utilize dual graphics cards at all so you would be basically playing on one GTX 760.

Single GTX 780 would be great, I just wish the price vs performance would be better.

If I had to choose a card now it would be the MSI GTX 770 Lightning. $220 cheaper, and 5-10 frames slower than a GTX 780. That's $22 for each frame for 10 frames, that's horrible. Plus cooling on the MSI model is amazing.

Heat won't be a problem. I choosed the Cooler master HAF XM and there will be a total of 9 fans in the case! :D (CPU fans included, without them only 5(Corsair H100i)). I will get the Corsair TX Series TX850 PSU which will be fully enough. I think i will choose 2x MSI GTX 760 Twin frozer edition because of the price and the performance... Thx for the answers...

Nvidia locked down cards because people overclocked and kill them... So the MSI lightning edition doesn't really mean anything now...

Food for thought: more fans does not equate to better cooling. The inverse is usually true. Air is not a good heat conductor. And more fans create more turbulence. Imagine walking when the winds are blowing directly at you in all directions. That is not realistic of course, but that scenario would not aid in your walking. It would actually be detrimental in your progress. But if you have a good stream of air flowing one way, it is much more manageable and if the wind is directed from your back to the front, then it would aid in pushing you forward. Same case here. If you blow hot air around the case with fans stationed at every edge, the hot air won't leave as quickly. It would boggle around in the case a lot longer.

So the point is to have good airflow, not more fans. Unless those fans are directed in a coherent manner, it can be detrimental to your goal of better cooling.

Actually I wasn't talking about the "extreme" overclocking potential (triple overvolting) that NVidia locked on those cards and that people didn't understand how to overclock them safely. Those cards (including the lightning) were THE FASTEST production GTX 670's out of the box. faster than the FTW series and was about the same at a gtx 680 in benchmarks. And whats hilarious is that even with that one part locked on the MSI cards, they still overclock better than anything out there.

And KSHAM is right again, It's called positive airflow. You need to have the air entering and leaving your case, not just all the fans blowing in.

That's the default setup on the HAF XM. A 200 intake in front and 140 exhaust at the rear and a 200 exhaust at the top.

So that works. You might add an intake on the side that blows on the video cards. I'd say see how it works out without it first and add as necessary.

haha must of posted that before I posted :)

But to be honest, and from experience with SLI, I would go with the single card setup. GTX 780 for one 1080p screen for gaming and rendering is perfect. Reason why I'm still doubtful about dual 760's is if anything happens to one of the 760's your down to one card for video editing.

how much editing and rendering do you do?

I will add 2x 140mm fan on the side and 2x 120mm fan for the hdds. I want to install a Corsair H100i(with the 2x corsair and 2x custom fans), but i don't know if i can install it without uninstalling the 200mm on the top. It says Top 200mm fan x 2 (1 is optional; converted to 120mm fan x 2 / 140mm fan x 2) I don't know if i can install the radiator on the top...

I render in cinema4D but that's mostly the CPU's work... I don't render very often(in cinema4d). But i edit videos more often, maybe 2-3 times a week... I mostly play games... 2x GTX 760 perform better than a single 780 and in some cases than the titan. Noise, power (and temperature) isn't but the price could be a problem... The rig with the 760 setup is 2500$...

I understand 2 gtx 760's are faster than one gtx 780, the point is that not only are you buying 2 lower priced/lower performance cards vs one high performance, your adding more heat, more potential issues (if ONE of those cards goes out, you go from great gaming to alright gaming, and you have to replace it to get back to its potential), and that 20%? a moderate overclock to one gtx 780 would make that nothing at all.

Not only that, but what about the games that don't utilize SLI? Now your really only running one 760. Or the editing software that doesn't recognize the other card at all?

To be honest man, If its a new PC don't skimp on that kind of stuff. I would spend the extra to bypass the heat, microstuttering, errors, and other things that come with sli anyday.

A review on newegg states there is not enough clearance at the top to mount a push/pull fan config with the h100 inside the case, though some have placed the rad outside. Apparently, you can use one set of fans with the h100 though.

One guy mounted the h100 with just a push config and took the 200 from the top and put it on the side of the case.

I think SLI setup is not prone to micro stuttering issues , ya he may need to wait for drivers to make the game playable at Dual Gfx System.
