Gtx 670 3 way sli 7680x1440

post #1 of 13
Thread Starter 
I am currently running 3 gtx 670 4gb in 3 way sli.

I am relatively pleased with the performance, but I am looking to get slightly better frames in games such as battlefeild 3.
Currently I hover around 40-50fps on all ultra with no AA.

I am wondering if adding a fourth card will offer any significant performance improvements or if it really wont do anything at all.

Not worth it, 4 way SLI is pretty terrible scaling wise.

At that res, I'd seriously consider 2 Titans. Titan performance really does shine over the 670/680/690 when it comes to the huge resolutions.

if we can see a pic of your screen setup running those 3 670's it will help us better drool.gif

It wont. I'm guessing you're mostly limited by the 2GB vram more than your GPU power.
Sell them all and invest in a better config. Something with at least 4GB of vram per GPU.

He says his 670's are 4GB versions. . .

Anyway. . .Wait for the 700 series cards. I know that's a bit of a wait but, unless you have the cash to make up the difference of selling your cards and getting 2 titans just wait it out.

Due to diminishing returns the more GPU's you add, 2x Titans would be the sweet spot indeed. Plus the extra vram is ideal for the resolution your running...

I agree, this is one of the few times titans make sense.

Sell your cards and get two of them. You will see better scalling and never have to worry about Vram for 2-3 years thumb.gif

I don't know what people are smoking.... I know this is OCN but he asked a very specific question... is it worth it or not?!

The answer to your original one... No adding a fourth 670 won't spew out more fps since your cards are at that limit.

About going from three 670s to 2-titans... If you were getting 100 fps... you will get at max 120 fps.

Now thats a 20% increament....

If you sell your three 670s => $350 a pop => $1050 the price of one titan... You need to add nearly 48% for 20% more frames.

You do the math.

As for those who are stating extra bandwidth is mighty fine for at that res... Running 3x680 4gb at the same resolution and I am having a dandy time in BF3... just turn off AA and blur.

You have anything to back the bolded part up? I'm not denying that it might be valid but it kind of seems like a number pulled out of the ether.

The price of 2 titans isn't that drastic compared to 4 4GB 670s, especially with used Titans going for 800-950.
