I have a question though, I don't really see any gains in performance, I'm still getting 40 fps dips in Borderlands 2, Crysis 3 still runs like dirt (which I expected) but I mean 680 lightning's in sli, shouldn't the performance be a little better? I only get like like 10-15 plus fps on maps in BF3, I kind of expected a lot more performance out of two lightning.

Excuse the long post, but I think I can help. For me, C3 performance has been mostly a matter of the driver version and driver settings. I've got C3 running smooth on max settings (both game and CP settings) @1920x1080 using a single 680L. I have no lag or stuttering and I never see any high frametimes. My framerate fluctuates between 40-55 using a 120 hz monitor. With 2 Lightnings in SLI, I'd expect to see 60 all of the time.

This is what works for me: First, the 314.07 driver is the latest one that works well. Any newer driver involving the Titan merge just isn't as good, and 314.22 has been outright awful for me with C3. Second, turn off vsync in game settings and choose adaptive vsync in nv CP. Third, set "prefer maximum performance" *globally* in nv CP. Setting adaptive power in global and max perf in the C3 game profile did not work for me. Fourth, SMAA works best with C3 using the game settings, with "application controlled" for AA set in nv CP.

A lot of games perform better if you cap the framerate in game or use nv adaptive vsync. BLOPS2, for example, stutters like crazy (on my system) unless the framerate is capped at 60. Then it couldn't be smoother.

Many other factors can affect game performance. There is a lot of disk IO for example. Do you have an SSD? That will help. If you have an SSD primary and HDD for storage, use the HDD for the windows paging file. Yes it's slower, but a non-bootable storage disk has very low IO, so the net effect (for me at least) is better performance on a slower disk. That works especially well if you have 2 HDDs; use the non-bootable one for your paging file.

I have a 3930k, which is a beast, and it runs comfortably at 4.4ghz. But your SLI should more than make up the minor performance difference in CPUs. Try my suggestions and see if you can't get 60 fps consistently in C3. And if they don't improve things for you, definitely let me know.

Thanks for that, I like a lot of info, I tried out installing 314.07, didn't seem to do much and I also changed the nvidia settings and that didn't seem to do much either. And yes, I have an SSD, I'm going to try out the page file thing tomorrow, I'm tired right now gonna get some shut eye. Also, I tried out Battlefield 3 and I realized I'm getting solid 85+ percent gpu usage on both gpu's

Not 100% sure with this, but 105° is probably the thermal limit, going over this value has a high chance of damaging the gpu rapidly. Under 105° is considered safer since they are reasonably sure the gpu will not die in a matter of hours at that temp.

Although 105° is the max allowable temp, it isn't good for the gpu to be too hot, so they set a throttle point at 70° to help keep the card cooler, they are pretty sure that the majority of cards will live through their warranty period sticking at that value.

Between 70° & the 105° max won't kill the card, but it may be that nvidia's research has shown that a larger percentage of warranty claims will be made if the cards run at say 80° for extended periods.
Nvidia makes those calls based on the reference cards, the ln2 bios on the lightning not throttling was MSI's decision.

As far as overclocking goes, it has always been the cooler the better. 80°C may be called the safe temp for a gpu, that just means it won't die quickly, if it is considerably cooler it will overclock better.

What you say makes sense to me, but I wish nvidia didn't make me feel guilty about letting my 680L hit 72-74 or so during an hour or two of game play each day. I mean, I know it's not going to kill the thing, but there is always that lingering doubt in the back of my mind smile.gif

Wish I could join you there, but being a family man, I have financial priorities such that my rig comes in at around 40th place smile.gif
