Dump SLI, or stick with it

I recently added another 670 to my setup and have been impressed with the performance... in supported games. Many of the games I have dont support it, and it really annoyed me when i tried Rome TW2 to find it does not support SLI, and looked positively rubbish with my one 670 utilized.
So now with the imminent price drop of the 780's i am thinking about selling my 670's and just going back to one card.
Will one 780 run everything maxed at 2560x1440 at 60fps as my SLI setup does?

I wouldnt get rid of SLI based on Rome 2. The whole way the engine deals with the graphics is borked and getting sli working wont make any difference. I have an [email protected] and 2 x 670's and in Rome 2 in big battles my gpu usage on ONE 670 is less than 50%... people with 3930x i7's have the same issues.

Rome 2 is trash anyway. One of the biggest regressions in a game series ever in my opinion ( and Total War is my favourite series of games...). What makes it even weirder is that Shogun 2 had great sli/xfire scaling and it is the same engine!!

One 780 wont be as powerful as your 670's in SLI unless you can get a properly amazing overclock out of it.
 
I understand your frustration and Rome 2 seems to be very similar to Rome in the way it is utilized (very poorly). The CPU is just as important in that game and not sure how many cores it uses, as I haven't played it. What CPU do you have? and one 780 will not run every game at 60 fps on your 1440P monitor sorry to say.

I have a 2500k @ 4.6 ghz. Mhhh, maybe best that i stick with my SLI then, The like of Metro and FarCry 3 run amazingly and i would hate to take a step back if a 780 will perform worse. I just wish it was a technology that was 100% compatible with all titles, and scaled 100% all the time! COH2 is another title that i play, but at reduced setting due to no SLI support.
 
Side point if I may OP - Anyone? Does a dual card like a 690 or 7990 count as SLI even though it's both gpu's on 1 card.

Do games that don't support SLI, take the dual card options as one card, or two?

You could flog the both 670s and get a 7990 :)

I did run SLI 680's with a 2500K at 4.6Ghz and in some games (well BF3 from memory), the 680's were being held back by the 2500K. In honesty, I could only notice by running monitoring software and the game always flew along but something worth mentioning.

It works exactly the same as two single cards.
 
Total war series are brutal for your gpu's.
I had Shogun II runing on my old PC, a 3570k oc to 4.2ghz, 16gb ram and evga slix2 gtx 660ti and had some low fps issues in larger fights.

However in near future it may be a good idea to upgrade for a single gpu.
R9290X or rumored 780 ti for example :)

It is brutal on CPU's not GPU's.

RTW2 is not that good on a Titan lol.

RTW2 isnt good on anything. There is a benchmark that shows a 7850 and a Titan getting the same framerate at 1080p....with a 3930k i7. i will try and find it.

Abysmal coding. It doesnt even look that great either!
 
As said above,a single 780 wont get you a solid 60 in every game. I have 2 and @1400p the more demanding titles will still drop under 60 but its a small price to pay for such a nice resolution. Have you thought about maybe selling the 670s and picking up a single 780 and when the prices drop add another? A single 780 will be more than playable and it surprised me how well it coped before I added a second

This is an option, however with the fact that SLI is far from 100% supported i doubt i would add another. I tend to play simulators a lot, and the extra VRAM would come in handy for FSX with all its addons.
 
The only 2 games I have played since I got my cards that dont support it are Rome and COH2. I'm not saying every game does but these days most games are
 
There is a hack around to make Rome 2 work on SLI.

Unfortunately CA and NVIDIA push the ball to each other about SLI support.

On the contrary, 24h after game release, AMD had drivers and profile out that supported CF on the game.

And I guarantee you on 2 7950s @ 1100/1550 with [email protected] is trully stunning game, without any fps drop when you control large armies (2+ stacks), and the AI turn is processed very fast.



FYI WOT doesn't support SLI either.
 
I am in the same boat
I have SLI 670s and found BF4 ran smoother with 1 card than it did with 2 @ 2560x1440, even though the FPS was higher (almost double).
I am hoping this was just the beta being a beta because I know I will spend a lot of time in BF4. If it turns out to be an issue with SLI I will have to sell them & just get a single 780, either that or get a new CPU because SLI does take a lot more CPU power to run in games like BF4. Selling 670s and getting a 780 is cheaper then upgrading my whole CPU setup
 
I found sli 670's to run pretty well in the bf4 beta, albeit im at a lower res of 1920x1200 and cpu is a 4770k. With bf3 though i did find an i7 930 @4ghz to be a slight bottleneck with theese cards when ran at the same res.
