SLI has gone to crap.

Im not sure what has happened but my 780 SLI seems to have more issues than ever.

BF4 stuttering and FPS random drops.

BC2 random 10fps drops

Random stuttering in certain titles such as skyrim.

No support for Dayz or any other green light or early access game. Have to turn it off completely for most of those as it completely breaks the games.

Im tired of having to turn it on every time the drivers update. Having to quit the game im playing and then quit a load of not related programs so i can turn it back on.

I had the same problems with my 7970 and CF. So this isnt specific to one or the other.

More frames seem to be coming at a HUGE cost these days. Im abandoning the idea of 4k and getting single GPU Gsynced 144hz and overclocking a lightning or classified card.
 
These are the issues which cause many people to recommend avoiding SLI/CF.

The random stuttering in Skyrim is likely mod related, which can go way past 3Gb of VRAM if you aren't careful. Early access games rarely get much love with multi GPU either. Your random 10 FPS drops may not be related, however.
 
Never liked it ever since the Voodoo2 days. Always seemed to have stability issues with games. Single card I never crash unless it's a known big with the game.
 
GTA V crossfire broke on the recent game update. It jitters all over the place now. You are not the only one.

Do the classified or lightning clock much higher than reference models?

They do, especially if you add more voltage. So, the better the cooling the better the OC. Especially if you go with a full water block.
Personally, I think I'll skip this gen and put a G10 on mine.

How does this work vs the power and temp limit on the GPU ? also does the voltage limit apply?

My lightning 780's seem to clock well but they are SLI so i never push them

Well, I have an AMD card, so no real power limit as far as I know.
For NV, I'd use some moded BIOS, Skyn3t ones are usually great. He usually takes more care of the Classy and Kingpin ones. That's what I did when I had a Classy (but I didn't watercool so it wasn't as important).
 
Skyrim has never played nicely with multi-GPU... not on AMD configs nor Nvidia ones. Now there's two types of stuttering. Your normal stuttering where the game seems to freeze for a split second. That's not caused by SLI... that's something else. Then there's micro-stuttering. The far more annoying (at least to me) stuttering that looks like a frame is skipped. You're running and suddenly it looks like he teleported a few feet. As if an entire frame was skipped. That... is caused by SLI/Xfire.
 
Battlefield 4 has been terrible with SLI since the game released. Having tried 5 sets of hardware in the game; 680s, Titans, 780s, 780tis, Titan Xs and all the driver releases across that span of time, I can say confidently it will not every be a good experience. This is even with a platform change from X79 to X99 and still the same stutter in the game.

I've been running a single card since the original Titans. The game is full of weird stutter in SLI, not sure how it's never been fixed. You even get the flickering textures under SLI still.

SLI has been losing its appeal to me. As single cards are starting to get really close to handling everything at 1440p it's becoming less useful unless you make the move to 4K. Games are still fairly stagnant in their performance demands apart from some fringe features you see added to a few games that tank your FPS. I think SLI/CF will just not be worth it in almost every case except for 4K once we get the big flagships on 16nm.
