To SLI or not SLI, that is the question

well 2x670s is quite good, and a non costly sli option and when overclocked can reach sli 680 levels depending on how good the card u get, and how it handles overclocking, but even stock sli 670s is quite good.

Adding the second monitor will not make it so you need more GPU power... Unless for some reason you try to play games with both monitors will the bezels right in the middle, so don't consider that a factor in getting a second card(unless you are going to get 2 more making it 3 monitors and then you could play in surround). Do you have the 2gb model or the 4gb? if its the 2gb you might want to run your games as you plan to be able to with 2 cards and check your ram usage... Sure the game might not be playable but seeing if the 2 gb of ram could be your limiting factor with 2 of the cards would be good to know.

What to expect if you choose to sli
Two GeForce GTX 670s In SLI (Tom's review)

As you can see I currently have the Asus GTX 670 DC2 @GB version and it OCd awesomely and no crashes, ever. I took it back to stock mode and it boosts to 1100 on it's own so I'm lucky in that department. I was also considering maybe selling this and just grab 2x7970 from MSI or Saphire and go from there.

I have the Asus GTX 670 DC2 and that is a 2GB yet it reads as 4GB when I click on properties. Weird I know. You really think that a single GTX 670 2GB version can push 2 x2560*1440 monitors without a huge drop in performance? And yes the plan is to have a 3 27" monitor setup by August.

I've read the charts before and thanks for putting them up. I might as well just get it or sell this one and push for 2x7970 for even better performance when I OC them. What do you think?

I guess I'm just going to stick with one monitor for now and cancel the order for the other one. I was planning on gaming on both of them by grabbing a second card. And this monitor does have one of the thinnest bezels around so when time comes 3 of them would be awesome. I want the GTX 7XX and AMD 8XXX here asap so I can make a completely new rig and dedicate this to wife in an HTPC case.

When I said push I meant gaming on both. I don't think it can. But I could use one for game and one for other stuff, if it came to that.

Yea gaming on 2 monitors does not really work... really only works with 1, 3 or 5. The 670 will support up to 4 monitors though but only a max of 3 for gaming. Two monitors would be like i said in my other post, only one used for game the other is basiclly just your desktop with whatever you care to use it for.

did you see the review from techreport about the frame latency on the amd 7000's.
the amd's run faster but nvidia delivers a smoother experience. amd could fix the driver issue next week who knows, which would make them the sure choice.

watch the 240 fps video to really see the spikes.


see how the amd has a bunch of fast frames then slow then fast, and the 660 only has a few spikes.
