I don't want SLi anymore, I just want a single card with less noise, less heat, less power usage and moar VRAM tongue.gif

I know I could wait for Maxwell, but it's sounding like it won't be out til Q4 (at least the top end stuff) and if you wait for the next best thing you will never end up buying anything as there is always something better around the corner.

I think you said it yourself "less noise, less heat, less power usage and moar VRAM." That should be enough to persuade you. tongue.gif

Shouldn't use the word "wait" when it comes to gpu unless of course you know an official date of the next line up of gpus. If you keep waiting you might have to stick with those 670s for a long time. People go on for years waiting for the next best thing but there will always be a next best thing right around the corner. So, no need to wait, just pull the trigger asap and be happy. biggrin.gif

Single gpu always has less issues than sli (fact).

I was in the same boat as you guys. 780 Ti now or keep my 670 sli.
My 780 ti showed up yesterday along with a new EK waterblock smile.gif
I have 8 hours to go here at work than it's go-time!!! biggrin.gif

From what I have read the higher the ASIC the better the card but my ASIC is pretty darn terrible 60.9% yet @ 1.187v (stock BIOS) my Gigabyte 780Ti OC X3 Windforce OC'd Core at 1185 boosts to 1272 in GPU-Z which doesn't seem that bad to me.

Is ASIC merely a computation process which has little or no bearing on overclockability or is my card a dud and you guys are all boosting over 1300?

I think the new B1 chips and the increased overclocking performance that was expected has somewhat panned out and negated the asic value. I have a 83.6 asic and by the looks of it so far, I should reach 1300+mhz no problem but apparently many 60's are getting higher overclocks also.

from my experience with higher/lower asic 780s/titans and having followed the 780 and Titan owners' club, there was overwhelmingly better performance from the higher ASIC cards (before the volt hack of course). I don't know, maybe it is an oddity but I've just always had better luck with overclocking results from higher asic cards.

Sorry for asking so many questions, it is my first time flashing bios to GPU, and I wouldn't be happy if I did something wrong smile.gif

1280mhz and going strong @ 1.175v no artifacts...TBC (next I'll try for 1300+)

Anyone know generally how much Mhz to the core can be added with an extra +35mv (or jumping from 1.175 to 1.21v)? I will eventually try it but I really want to keep my volts/temp down for gaming since my card is going in an itx case.

(random question) What's the average fps a single 780ti gets in a maxed AC4? I've just started downloading the game.thumb.gif

Hi, I've had the same experience, running at about 1270 mhz, at 1167 volts I believe, but still at 1.212v I only get a max of 1300mhz stable. I think it's more about being able to provide stable voltage levels. Maybe at the higher voltage setting the voltage level is more unstable. Thus making games crash.

As for AC4, that game is also very CPU dependent. I have a i7 860, at 4.1 ghz, and it's a bottleneck for sure. Especially when you look over the city, frames drop to the 40's (running at 1440p). Enabling MultiThreading in Nvidia Conrol panel helps dividing load across cpu cores. I get best frames with my CPU clocked to 4.5GHZ without HT. And when you open Taskmanager (I have windows 8.1), and go to the performance tab, you'll see that the first and last core are heavily occupied. And when the first core is at 100% utilisation, the frames drop and stutter occurs. That's with complex environments and lots of activity. Even when the rain sets in, the frames drop and CPU gets utilised at 100%.
I think you won't see 100% utilisation with HT, ever (in games that is). So it's not really a good measure to say, ah well, the game only uses 70% of my cpu so the cpu won't be a bottleneck. It's more about how these threads are devided over the cores.

Of course when you go for high AA settings etc, then the GPU will become the bottleneck before the CPU does.

I also had the same problem with AC3 (at 1080p and 580SLI) and with Far Cry 3. These games are heavy on the CPU in my experience. You'll hit a wall and that's why benchmarks won't see a huge improvement when it comes to Single GPU versus SLI. In far cry 3, I had about 45 fps average everything on ultra, 4x msaa, with a single gtx 580. When I put in the second 580, I got an average of 60 fps (v-sync), but once again, with heavy CPU load (a lot of shooting going around) and complex environments, the frames would drop to mid 50's.

So, keep that in mind.

I'm getting a 3770K this weekend. smile.gif

And you use the modded bios?
What kind of differences have you noticed?

Thanks for the info man!

Hopefully a 3770k is sufficient for both you and me!biggrin.gif

Edit:
Just did a valley run 1305mhz @ 1.175v no artifacts...Keep in mind I've only tested these clocks in valley and have not overclocked memory at all yet. Just taking my time with this card.

I sure hope so! I will be OC'ing the hell out of that thing. tongue.gif I'm sure going to go at least 5ghz, hopefully temps will remain low (after a few hardware tweaks wink.gif )

EDIT: you could also lower environment details to achieve better fps, but then you will noticeably see people and buildings fading in a lot more.
